The fears that caused the fall of the asteroid, on the one hand, are not without a basis, but on the other hand, they are significantly overblown by those who are eager for sensational "horror stories" by means of mass information. Asteroids, as a great expansion of the celestial body, which conceives a majestic ruinous force, already more than once or twice in the history of the Earth "saw" our planet. With so many hysterical forecasts about the chergovy "asteroid-driven" that is approaching the Earth and the axis-axis is ready to fall on our heads, sound no reason for anything and will continue to ignore the data of the scientists.
Asteroid is a frequent guest on earth
In this hour, fahіvtsі-astrofiziki do not guard near the “outskirts” of our planet close to our planet the All-world of asteroids, as if they would become a real nebezpeka. Navit widely advertised the asteroid Apophis, which passed in 2013 for 14.5 million kilometers from the Earth, appearing not so scary, as it was advertised by the deacons. New motherfuckers demonstrate that when turning in 2029 the Apophis rotation for the current situation cannot be closed from the Earth. However, if such an asteroid with a diameter of close to 300 meters was left behind, then the ruinous traces of the fall of the asteroid would be less on a local scale, at a distance of tens of kilometers. Asteroid-driving, whose diameter exceeded bi-kilometer, is not visible to space in the nearest expanses.
Tim is not less, but it does not mean that the Earth has never collided with asteroids - at the moment, hundreds of craters are close to being repeated, which are traces of similar zitknen. The actions of these asteroids were more and more significant. Nearly 37 million rocks on the territory of Siberia fell into an asteroid with a diameter of approximately 5 kilometers - the crater of Popigai is about 100 kilometers. 65 million years ago, our planet saw the most famous asteroid - near the Mexican Pivo Island Yucatan, an asteroid with a diameter of 10 kilometers fell (the crater was depleted by it about 174 kilometers). For one hypothesis, the very viklikana tsієyu podієyu global “nuclear winter” and brought dinosaurs to the extinction, as well as many other types of creature creidy.
Don't stick around with the asteroid
Navitably small, a sprinkling of dozens of meters across, the asteroid, when struck from the Earth, brought up to the sight of energy, which is good for the warhead of an intense atomic bomb. I realized that it would happen in a densely populated area, which would lead to colossal ruins and the number of victims. But the main respect for science and science is attached to the great asteroids, the diameter of which is calculated per kilometer. More people will chirp that it will be like a great asteroid to fly to us in a right way and some kind of death may be heavenly body, to put an end to the life of the Earth.
Here varto once calm down. Sob mittevo znischiti life, to destroy our planet, the required asteroid with a diameter of over 100 kilometers. Such asteroids have not yet been fixed in space. Asteroids with a diameter of close to 10 kilometers in the house of science us forwarded from historical material. Confinement with such objects does not carry a fatal threat to the Earth, but it is not easy for the bagmen to get there. Nasampered, more likely to be yaknaydali in the event of such a “heavenly guest” landing, because a crater with a diameter of at least 100 kilometers is established, for which nothing alive can be lost for the purpose. At a radius of up to a second thousand kilometers, it will also not be necessary - the most intense earthquakes will sweep through the territory. Like an asteroid falling into the ocean, it will lead to a stingy tsunami. 
, yak not to flood the whole land, but for the coastal regions it will be fatal. It will be necessary to walk either on hundreds of kilometers of coals of the mainland or on the great island (the other islands are not particularly welcome), or at a height of at least 500 meters above the sea level.
Asteroid and positive effects
Ale є fahivtsі, yakі bachat in essences with asteroids is no less negative consequences. For їhnіm allowances, the very basis of the Earth's life in all її raznomanіttі can be the last fall of an asteroid in the past. The second version, that the very life of that yogo development is direct, that there may be the last evolutionary results, vinyl under the influx of a series of drops of asteroids of various sizes is close to 500 million years ago. Same asteroids 
and created by them special minds of the middle of life and plunged into a surge of biological activity and brought to the point of vindication as such an earthly biosystem. However, these hypotheses are still entirely speculative and do not know confirmation.
According to the data of archeology, the annual streak of biological activity, about 500 million years have not been recorded. Before that, it’s nice to explain, like the very same zіtknennya with asteroids, like they’re flooded for hundreds of kilometers, literally boiled the earth for themselves, they could take some kind of biological splashes.
What work?
There are only two options for the manifestation of the great asteroid, the trajectory of which, with a high imovirnistu, brought it to the ground from the Earth, in fact, there are only two. The first one is passive, and the second one, when transmitting a high accuracy of estimating the parameters celestial body that yoga fall on our planet. In this fall, in the future, they designate the place of the landing of the asteroid and open up that area, so as to lean at the zone of ruinous factors of the fall. Because of this, there is a large-scale evacuation of the population, trade pressures and cultural values from the regions of risk to safe areas.
The other option is active and more distant - change the trajectory of the asteroid, so that you change the course and fly over the Earth. Here already there are a number of different technical scenarios that are connected with specific characteristics. In this case, such signs are even more important, as the mass of the asteroid itself, as well as the moment of its manifestation, that hour of the transmission of darkness. Scenarios and different: vibrations at drillings in the asteroid glybin mine of a nuclear charge, fixing on the asteroids of the hard drive or sleepy windows, changing the direction of the rotation of the celestial body under the influx of space vehicles, which are fired by them.
Oleksandr Babitsky
Nebezpeka for civilization can be like that of the people themselves, so be the same. Let me tell you that for the best understanding of the world of science, readers simply need to be aware of these familiar problems. I want to get rid of their part.
First, what can you save people for a thought, if you talk about unsafety, like threatening our planet, tse. Such a splash of ZMI and Hollywood films. About other nebezpeki wide zagalu vіdomo rich less. Well, well, let's see...
Journalists and Hollywood did not come up with anything new. The Earth repeatedly recognized the empty asteroid bombardment. And more than once more often, judging by the fact that it often happened earlier.
Let's guess only a little bit of vipadkiv, which will be enough to put down the enemy.
Since then, about two billion years ago, asteroids fell on our planet, and it is possible to compare them with Mount Everest. After the impact, a crater with a diameter of 140 km appeared, which is near Pivdenny Africa. I don’t know what to lead to which crater of tourists, but to the famous crater of Arizoni (America) to lead. Its crater is 1200 m in diameter, 175 m deep. The crater copes with a stronger attack, especially in the wind. But in the winter, which fell on our planet before the new, the Arizona meteorite is just a sweetie.
One of the greatest catastrophes in the history of the Earth happened about 250 million years ago, like the Permian period. The impact of an asteroid, which fell here between Australia and Antarctica, would push the flooring, which called for a massive eruption of volcanoes near the area directly opposite - near Siberia. As a result of the face of the Earth, more than 90% of the ridge sea creatures appeared. Life was practically erased from the face of the planet, the evolution had a chance to start mayzha from the cob.
Insha, a little less than the scale of the catastrophe became close to 65 million years ago. Todi did not spare the dinosaurs. The asteroid is larger than 15 km across, having fallen near the area of the Mexican inflow, not far from the Yucatan Pivot Island, where a crater with a diameter of about 200 km was filled with a riddle about it. (Before the speech, deyakі vchenі vvazhayut that the Mexican inflow itself is nothing else, like a crater in the impact of an asteroid.
An intense seismic wind swept through the center of the planet, which played the role of a kind of “lens”, and focused on Hindustan, which was just opposite, like an island at that hour. Through the cracks on the surface of our planet, billions of tons of melted basalt were thrown. The impersonal new volcanoes threw into the atmosphere a neimovirn kіlkіst sang, shading the Sun. The lack of sleepy light led to the cooling of the Earth, after which, the ice age began and the death of dinosaurs, as if they died in a record term for evolution.
Let's look at the descriptions of the vipadkіv, є craters, vіk of which are estimated at 125, 161, 295, 330 and 360 million rokіv ... Respect the periodicity. The rest of the Great Zustrich was born 65 million years ago. The time has come for me to chat again. For a long time there were no unfortunate guests, skins of whom for us were dear to all the Tatars, they were taken in at once ... and in a rage, the guests “pіdyaguyutsya”. In 1908, a comet swelled off Russia near the Pidkamyanoy Tunguska region. The first comet was like that, and the roses about it were stuck on the side. To that, the comet showed on a micro scale what would be from the Earth, shutting itself out with a larger object ...
In principle, people were spared the same way - if you fell into a larger populated area, the history of mankind could take a different path. Yakby, having fallen less than six years later, his name would no longer be Tunguska, but Moskovsky. Zvichayno, Moscow bula would be poor. Another year of the call - and bov bi sterty from the face of the planet Berlin. On the right, the strength of the vibuhu of the Tunguska meteorite became close to 20 megatons! For the sake of argument: a total of 15 kiloton bombs were dropped on Hiroshima, and 20 kilotons on Nagasaki. A thousand times less vibuha at Pidkam'yanіy Tungustsi!
Despite the fact that the Tunguska meteorite vibrated at a height of 10 km, the century-old forest of vibrations over an area of 2150 hectares. The shock seismic wave of the two (!) overtook the Earth. After the vibe, not only in Siberia, but also in Europe, for many days, there were more nights and the gloomy weather was watched - so richly the saw was stubbed in the atmosphere of the song after the repeated vibuhu. Moreover, the diameter of this meteorite became less than 50-60 meters.
1996 rіk, a herb-asteroid with a diameter of 500 meters, spanning a total of 450,000 km from us, and after sixty more one asteroid, with a diameter of 1.5 km, having approached our planet by 3 million kilometers. Behind the cosmic worlds there is order. 1998 - asteroids "whistle from the crown" three times - at the fierce, spring and leaf fall. In 1999, roci - in birch and in chervni. Two vipadki bulo 2000 roku.
What will happen if a great asteroid hits the Earth? Doslidniki rozrahuvali the process of catastrophe on computers. When an asteroid falls, which is only one kilometer in diameter, everything that is within a radius of a thousand kilometers from the catastrophe will be destroyed. Pozhezhі zahoplyat majestic territories, in the atmosphere colossal number of people singed that saw, which osidatime stretched out for a long time. Sonyachnye promeni cannot break through to the surface of the Earth, through a sharp cold day perish a rich view of heat-loving growths and creatures, and photosynthesis takes root. Come those who can be called nuclear winter. Most people and creatures will die of starvation.
And if it was possible to drink the precipitation and circulation of the atmosphere, the greenhouse effect would be blamed for the increase in carbon dioxide in the atmosphere. The temperature at the surface of the globe will rise, which will cause the flooding of the coastal part of the land to melt the polar ice. In addition, the magnetic field of our planet will collapse, the dynamics of tectonic processes will change, and the activity of volcanoes will increase.
When an asteroid falls into the ocean, the consequences of the impact will be no less stingy. The land will be flooded with gigantic tsunami, and may I see you die all the same, may you live on all the coasts of the earth's backwoods. The water drank, which, having consumed it into the atmosphere, will again change its circulation, but it will not be possible to change the climate.
Offending options are ruinous for civilization. Guessing, go about the body with a diameter less than a kilometer. At least the chances of perishing in such a catastrophe of the entire human race are no less than the chances of a sane person perishing in a car accident. What does it mean? Today I feel like reading a link about those.
How many people died in an accident, naivly vvazhat that already we are definitely mine cup of cya. Ale yakbi, our planet was a member of a galactic symbiosis of about six billion members, we were only informed about hundreds of thousands (!) of dead species of asteroid civilizations. Hundreds per day.
The first, who seriously marveled at this problem, was the US order. Beginning in 1981 NASA regularly conduct for the sake of the asteroid problem. In 1991, for the sake of international character, a scientific group was created for the sake of an international character - with the initiatives of NASA and the International Astronomical Union, a working group was created to investigate objects that are approaching the Earth. The Americans developed the project under the name "Cosmic Varta". We are transferring the deployment of six 2.5-meter telescopes on Earth, as a way to ensure constant monitoring of space. For the support of this project, accurate data about the movement of asteroids into space, calculate their trajectory, mass and speed. I, perhaps, turn around, hitting the asteroid with nuclear warheads.
The main culprits of the nuclear project are American nuclear scientists, under the cerebration of E. Teller, honorary director of the Livermore National Laboratory of the USA. You know that the time has come for a long time to develop experimental vibrations on one of the asteroids, which they fly by, to improve the technique of delivery and navigation of charges, evaluate between our technological capabilities.
But not all vcheni support this project. It’s good for someone to shoot down asteroids from an unsafe course, to shoot at yoga ... with lead ingots! A blow of a rich-toned lead ingot as a whole can destroy asteroids by a tenth part of a degree from a deadly path, and for the right roses, it will be enough.
Even more promising is the use of high-intensity lasers on the surface of a space body. First, change the mass, viklikane with a sharp vibram of speech, but by itself it will lead to a change in the trajectory of the flight, and in another way, the flow of gases may become for the asteroid its own jet engine.
Hell, we can just fly to the asteroids and stay on the surface of a sprig of space engines, transforming the asteroids into one giant rocket. The launch of rocket launchers is on course ... Utim, for now, everything is a fantasy, on the right of the future, it is necessary to live up to what is required. Ale, in the “asteroid” mood, even if the prospect of the culmination of the problem is shelling. And what will you punish robiti with new innovations?
Overnovy, as it seems, they call the stars that vibrated. To our yellow dwarf, it’s not safe to transform into a new one in the nearest future one, I don’t threaten it, but the real stars - more massive - can throw out a similar focus.
At the moment of the vibration of the supernova, the sky vibrates the style of energy, the sky of the Sun building vibrates for 5 billion years, that is the star that vibrated, shine like a five billion Sontsiv! Do you think the stars are far away and they won't chain us? It's a pity, as if a similar "radius" will appear in the radius of 25 bright rocks on the Earth, it will inevitably remove its "scar" on the Earth. Streams of ultraviolet, x-rays and gamma-ray vibration reach our planet and damage the ozone ball.
To be a break, yakі not drag on for decades. A hard sony ultraviolet for a whole hour builds plankton - the basis of the grub lancet near the Light Ocean. The masses of wild living creatures will bud at the ocean, that buv and land. Under the influx of cosmic prominence near the upper spheres of the atmosphere, it sharply increases in place of nitrogen dioxide. The smallest droplets of this gas make mist, which burns the Earth and cools the atmosphere. Unacceptable...
It's getting hotter, which means the star will vibe a little closer. It’s already been bolstered that it’s the hour of the night of the supernova star on the sky 10 bright rocks on our planet, the amount of ozone in the earth’s atmosphere will shrink twice.
How big is the problem? In our Galaxy, the sleeps of the new ones are guarded on average for 50-100 years. For the time being, we were just happy - most of the new stars were torn so far into the Sleepy systems scho mi navіt did not commemorate them. In the uninterrupted proximity to us, that on the vіdstanі in the splendor of dozens of bright rocks, the vibes of the new stars are guarded approximately once in a couple of hundreds of millions of rocks. Imovirnist tsієї podії is approximately the same as the possibility of falling on our planet an asteroid with a diameter of tens of kilometers.
Prote similar to the Earth has already been! Not only did the asteroids destroy the rest of life on the planet, but they burned the new ones. In the mid-1990s, the physicist John Ellis of the Swiss CERN and his American colleagues Brian Fields and David Schramm let it slip that the new vineyards had lost their traces in the ice balls. On the right, in the one in the gas fired shells, as if she threw off a star from herself, a right chemical factory was started. For a short period of time, the entire range of Mendeliev's tables is shown here, right up to such a transuranic element, like Californian (serial number 98), like the Earth can be taken away with a piece of the way.
Like this chemical gloom, thrown over by a new star, covering our planet, then exotic elements penetrate the atmosphere. Having settled on the surface of the land, or on the bottom of the sea, the stench is filled with the same unimaginable, like and ti, that are overwhelmed after the fall of the majestic asteroid. (A meteorite, having killed the dinosaurs, the manifestations of the phenomena, to that having robbed the ball, which spread the last days of that third period, the majestic quantity of iridium.)
Like, let's say, the sky is vibuhne in 30 bright rocks around us, then the mass of speech that has been spilled onto the planet, the stock is close to 10 million tons. (Which shaved with a total diameter of 200 m.) Tsya mass is 10,000 times less than the mass of an asteroid, which crashed into the Earth 65 million years ago and saved dinosaurs. And if you lie that the speech of the supernova did not fall into one place, like an asteroid, but spread all over the planet, then it’s really important to know. Prote yogo can see some isotopes that are not known on Earth: for example, zalizo-60 and plutonium-244.
Dovgoochіkuvane vіdkrittya, as if, it came unsatisfactorily. A group of German physicists on the choli with Günter Korshinek, volcanic volcanoes, vipadkovo showed a 60-degree temperature in the clades, recovered from the bottom. Pacific Ocean near Pitkern Island. Vzagali, vcheni carried out іnshi dolіdzhennya. The stench took the specimens of manganese-rich concretions from the upper part of the ocean. Qi Shari, what revenge large number bay and manganese, often appear on the outskirts of underwater volcanoes. The axis here is the number of manifestations of the isotope in the colony, which exceeded the norm in a thousand times.
The period of the fall of the fall is 60 days before the second of millions of years. Vcheni virahuvali that this portion of the isotope wasted into the earth's atmosphere nearly five million years ago, and then settled on the ocean for days. The reason for the appearance of a sun-60 moment was less than a sigh of supernovae, which was known for 50-100 light rokiv in the Sun. At that hour, the star shone sing-songly on the sky a hundred times more brightly, lower than the new Moon!
According to the estimates of astronomers, from the hour of the birth of life on Earth (for the rest of three billion years), on the outskirts of the Sonyachnaya system, a sprat of new stars swelled once again. You can admit that these cosmic catastrophes have littered the evolution of the life of the Earth. I not on shorter.
Ale іsnuyut at the All-World and still unacceptable speeches, lower vibuhi of new ones. Por_vnyano recently, astronomers discovered the most recent phenomenon. How yoga was not marked earlier, unreasonably. Z'yasuvalosya, scho navkozemnі satellites, yakі lead vigilance for the All-world in the X-ray range, the skin of God's day register at my little corner of the All-world a sharp sleep of gamma-vipromonition. Spalakh threevae only a few seconds, or to inspire a few seconds, but then the oppression is majestic: for a fraction of a second, stilki energy splashes, how much could vibrate the Sun for ten billion years!
Vcheni still can not understand, the stars are taken such a stingy energy. Possibly, tsі motoroshni universal bliskavki spalahuyut, if the neutron star znikaє in the womb of the majestic black diri or if they stick. As a rule, such dreams are guarded beyond the boundaries of our Galaxy. And what about a "bliskavka" bliss in a radius of 3500 light rocks from our planet? It happened that at the same time b stylki of charged particles rushed to the Earth, a few reached її for the remaining 100,000 rokіv. There will be a stronger radioactive infection after that soil! The first dose of yoga will be lethal to all living things. For a month, half of the population of the earth's kuli vre. The other half of the day is three times a year.
Possibly, the greatest death of creatures on Earth - the “Permian catastrophe”, which became close to 250 million years ago - was the viklikana herself such a spalah. For deakim tribute, under the hour of the Perm catastrophe, 96% of the planet's inhabitants became victims of the unstoppable sea. The most famous trilobites have appeared from the Earth. The reason for the tragedy of dosi was left unattended.
Other troubles are holding us back. The rest of the dozens of millions of rokivs The Sun is near a perceptibly calm place – between two galactic arms. However, the Sonyachna system wraps around the center of the Chumatsky Way (that's how our Galaxy is called, like komus tsikavo) and in a song hour it will see into the region of the galactic arm densely seething with stars.
There we can spend as many as 60 million years. Numerical stars will bring chaos to the gravitational order of the planets and comets of our system. The impersonal comets from the so-called Oort cloud, which dozed on the periphery of the Sonyach system, straight up to the center, inevitably clinging to the planets, including the Earth. Even harder, as the Earth itself changes its orbit, moving a little closer to the Sun, or a little farther away in sight. It is unlikely that a person can live on a frozen, baked planet.
Ale, navіt yakscho all tsі nebezpeki us to go away marvelous, all the same in some hour you will need to get ready to say goodbye to the sun. Vono become old, pretend to be a red giant and clay the Earth. Tse become not once. The sun gradually rises up. The earth will also be step by step covered with a desert, which will lead to the mass extinction of creatures. Through pіvmіliard rokіv the Earth will be simply boiled. And after five billion years, the Sun will be blissfully blown away. This land may be farther away from our planet, and the Earth will be covered with a viscous, baked mass, which predicts volcanic lava.
“Reasonably, we will not sit with our hands clasped and calmly check, until the pitiless All-World will tear us into ganchirki! - Whip romance more expensive space. - It's absolutely disgusting! First, you can fly somewhere with your belongings. In a different way… In a different way, I know you. More gave. And we'll take care of it there."
Tse good option, romance, but it's a pity, let's fly over to the other side of the world in our Galaxy, if there are no cardinal problems. On the edge of misfortune. Chumatskiy Way to rush at speed of 500,000 km/s near the far side of the galaxy - the famous Andromedi nebula. Galaxies are approaching ten million kilometers each day. Narazi to Andromedi lost 2.2 million of light rocks. A child of a task for the first class: in what hour will the "go" shut up?
No, it will be beautiful to wake up: when the “pozdіv” are close, you will be able to try such a nameless number of stars that people can read a newspaper at night without burning the light. And trohi pіznіshe (through yakіs chotiri-p'yat miljardіv rokіv) newspapers are readable to no one: Chumatsky Way zb'єtsya z nebula Andromedi. I sing, tse bude is not a sight.
Is it possible, do you think, that the shards between the crystal stars are already great, the galaxies will go through one crisis without remembering? It's a pity ... Seen between the stars in truth hundreds of millions of times, I change the diameter of the stars themselves. There is no empty air between them, but there are majestic masses in the edge of the rarefied interzonal gas. Vin, how to transfer, and cause a catastrophe. Invisible to us at once, through the expansion of the gas, the haze will heat up and fall off after the storm. A thermonuclear reaction will start to swell in their thicket. New stars are being established. The stench is counted in thousands, and even hundreds of thousands. Їх rozpechenі masi vipromіuvatimut brightly brightly. Poohmura cosmic far away the axis of non-flowing fireworks. The axis will only marvel at the new one, there will be no one.
What are our chances? І chi can we help the world to help me?
I'm on the verge of being able to… Nature works from a reserve. 99% of the first speech of the All-World was annihilated in the first meeting. Thousands of biological mutations, one is successful and fixed. Three thousand nasinnya kulbabi sprouted one or two. A lot of local civilizations on Earth did not face the crisis and perished. Now we have a connection with globalization in all of us practically one civilization from the great letter. Tobto, at the same time already go about life on the planet vzagali. As if, now we don’t seem to be living in one outskirts, covering the entire world economy. Together with us. Possibly, from dozens of hundreds of civilizations, like "hanging" on different planets of the infinite space, global internal and external crises are alone, so the survival of civilizations is no more, lower in our country kulbabi. It's not good.
On the other hand, in the world of evolution in the All-Suite, the role of reason is increasing and the role of physical factors is decreasing. Take a global physical map or a map of growth, marvel at America or Eurasia. Kudi forever, well, for example, on the lower third of Eurasia - a zone of forest-steppe and steppe. More precisely, lie down by nature, so that there is a forest steppe here. We really know the villages, the towns, the open fields, the power transmission lines, the ditches and canals, the mines, the airfields, the threads of the roads… In the rain, the natural forest-steppe in a clean-looking mayzha has been lost. So it is just like in the European taiga ... In the countryside, there may be more than coma and birds. And more aircraft fly with helicopters.
Lyudina has long ago become a geological force that changes landscapes, which signifies Vernadsky. Before the speech, under the noosphere of the vіn mav on the uvazі itself and only tіlki tse - pouring people into natural landscapes, but not those that show esoterics and exalted ladies with raspberry hair, slender to folding natal charts and deep-thinking reflections about spirituality and about the information field of the planet...
Injecting the intellect like the power of a well-organized matter to transform nature (minimize the natural middle ground on the piece) in the world we grow more and more, than we give time to progress. Zvіdsi admission. Why would the civilizations that appeared in other dawning systems earlier for us not take on the role of a “breeder” or a doctor, who piece by piece promotes the “similarity” of civilizations? You don’t feed an adje child in a canopy booth; But you can’t - put yoga in a pressure chamber and start to recover.
Why should they follow us for a long time? And they only get into the extreme vpadka, through the dribnitsa, at the sight of Hiroshimi and Nagasaki, they don’t get involved. Tshomu has sens. As if the illness of a child is easy, the temperature is not too high, there is no need to beat it: the body itself resists, so you can induce a small training of the immune system. Ale, even though the temperature is too high, її begin to beat with faces. Also, as if we ourselves don’t fit, as if we’re not really safe for spending the cosmic spirit of the earth’s civilization on fire, the stench will fly in and they lie to us, not nourishing. Splashing on the hollow - breathe! Abo to put at the "pressure chamber".
Beautiful version, ale Nazaretyan casually calling it one of the varieties of religion. Modified in a modern way by a craving for the Old Man, like, at a different time, come, vryatuє, vіdshlopaє ...
Mabut, vin maє ratsіyu ...

How skeptical people were not before the Hollywood story about the fall of a giant asteroid on Earth, yet space can be a serious problem for our planet. The most real threat, behind the great rahunka, is to go out of the depths of the unassailable All-World.
It was established by the vcheniy that the history of the planet was more than once clogged with asteroids, and moreover, there are serious traces. This explains the respect of those who are not safe for the asteroids. To such asteroids one can see those, hypothetically zіtknennya, which from our planet can lead to the death of mankind. So, NASA scientists have revealed over 150 celestial bodies, as they carry a potential threat to human civilization.
The topic of "attacking asteroids" has recently become a topic of interest for everyone. So, the fall of meteorites up to the other half of the 18th century was taken for Oman Zora. Fahivtsі in the 1960s tried to explain the appearance of craters by "earthly" reasons. Ninі їkhnє kosmіchne pozhennya do not foresee everyday sumnіvіv.
So, the death of dinosaurs is recorded on the "conscience" of an asteroid, the diameter of which is about 15 kilometers. 65 million years ago, zimknennya z this asteroid at once from the dinosaurs ruled in that world about 85% of the species of roslin and creatures. After the fall of the giant asteroid, a crater was created, the diameter of which became 200 kilometers. Billiards of tons of water vapor and saw, and also drank that soot in a stingy fire rose into the atmosphere. Everything for a lot of months was darkened by a sleepy light. This could lead to a catastrophic drop in the temperature of the Earth.
Є impersonal transmission of facts, as if they indicate the end of the world in 2012. Ale, as it will become, no one knows. The earth is less than a cry from the All-world, as it appeared as a result of the interaction of cosmic bodies, and it is not included, which is also known. The fall of the asteroid, nayimovirnish, not destroying the planet itself, but to allow її people, creatures and roslin, tobto. kind of life. Will the Earth scatter on the faceless ulamkiv? Chi, can you pretend to be on Mars? For the time being, it’s possible to be less shy, relying on the data that NASA is spreading with a wide streak.
Asteroids and comets often fly past to bring unsafe proximity to the Earth, and to cause the least damage to their trajectory can lead to indelible memories. Yes, yay comet on the ice floes, you will become the cause of the shinny, global warming, and also the wind. Deyakі vchenі stverdzhuyut, that in the entire history of the planet Earth won close to 6 times stuck with the asteroid. To speak about these craters, the occurrence of which can be explained only by the fall of an asteroid on Earth.
The effects of an asteroid fall may be different. To lay everything in the form of an asteroid, mist, in a vein in the fall, that kind of swidkost yogo ruhu. So, for example, an asteroid with a diameter of close to 500 km caused the death of all living Earth, moreover, by stretching it out. The impact force is stronger than the fire storm, as if you were all alive to your way. Less, lower for good, hvilya death around the planet and plunder on it all alive. It’s completely imaginative that the simplest organisms can survive and start the process of evolution on Earth anew.
An asteroid, which has a smaller diameter, when falling into the ocean, can cause a giant tsunami up to 100 meters. Such a sickness can be taken from the planet for kilometers of the coastal zone. Such a tsunami, to the last, can cause a low number of man-made disasters. As if the asteroid fell on the same mainland, it hit the blasting gigantic part of the land. Everyone lives on the planet of death.
Chi varto ochіkuvat such a world of light? Emi Mainzer, one of the practitioners of NASA's Jet Rocket Laboratory, affirms that hundreds of asteroids are wrapped around the Earth at once, the building blocks on the planet are all alive. The chances of a planet hitting an asteroid, for the sake of calculation, are not great. However, it is not possible to be completely incapable of anyone else, the oskelki space is absolutely intransigent. Possibly, the unsafe asteroid itself can fly to the Earth. Technologies to communicate quickly develop rapidly, prote, unimportantly on the spot, as long as there is no system, so that it could give accurate information about the movement of all space bodies. Ale schob to reveal all the tension of the potential problem, to marvel at the expansion of the asteroid belt around our planet.
Mars is closest to the waist. At the present moment, it is even richly proving that life was on this planet, but for unknown reasons it perished. The largest and most modern version of the death of an asteroid. The strain of the whistle, which hid at the blow, vanished all the while. The earth can become an offensive victim as a whole, shards of it will reach close to the belt of asteroids.
So, like Morrison and Chapman, they say that once every 500 thousand years on the planet there is a global catastrophe through the fall of asteroids. Behind the statistics, the asteroids rose from 10 kilometers of skin fall for 100 million years. The stench may not deprive the people of that creaturely world of chances for survival. Vcheni vvazhayut, scho in our hour becomes such a zіtknennya, then perish all the people. Behind the fahіvtsіv's permissions, the greatest threat is to walk in the heavenly bodies, like a mayut average value. Over 500,000 deaths, as a result of the fall of such bodies, more than a billion people perished behind the pіdrakhunkami of experts. The earth was constantly bombarded from the side of space.
In this hour, behind the roses of science, the most safe for our planet, there are such asteroids, like the asteroid YU 55, Eros, Vesta and Apophis. About those who are a real threat from space, they started talking only once, if they knew the asteroid Apophis. The diameter of a yogo is about 270 meters, and that of a vaga is about 27 million tons. Zіtknennya of this asteroid from the Earth, for the rest of the tributes, it is possible for 2036 rotation. You can’t go to Earth like this, you can’t fall, you can lead the original shkoda of space technology. We can get closer to the Earth at a distance of 30-35 thousand kilometers, and most of the space vehicles operate at such a height. Apophis present moment vvazhaetsya first among the potentially unsafe heavenly bodies. In 2013, it is possible to fly perceptibly close to our planet and in the future, it will be possible to protect the right nature of the threat and to signify that it is possible even to avert catastrophes.
Russian vcheni did not become checks of 2013 rock and created a group, so that they would be victorious, that they would work, that they would say that Apophis from the Earth would still be. The approach of the asteroid in 2029 will change its orbit from the Earth, so the forecasts for a further direct rush are even more insignificant without more data. After an asteroid strikes the surface of the Earth, according to previous estimates, there will be the most intense vibration of 200 megatons.
Also, from the Earth, the asteroids 2005 YU 55 are constantly approaching the singing periodicity. From that hour onwards, one of the safest asteroids is introduced. The largest asteroid in the belt is Vesta, which is visible from the Earth with an invisible eye. It is explained that it is possible to approach the planet at a distance of 170 million kilometers. There are many such potentially unsafe asteroids.
But, no matter what, astronomers don’t give the Earth any serious trouble from the side of asteroids. But, as it was said before, the cosmos of non-transfers, that behind potentially unsafe objects is constantly guarded. For whom especially dark cosmic telescopes are used, optics are especially sensitive. Without them, it's easy to finish the asteroids, the stinks of the stench invigorate the light, but they don't defy yoga.

If the asteroid crashed into the Earth, its kinetic energy (and this energy is great for a massive body, to fly on a high speed) turned into thermal energy. Shards of thermal energy are seen in a short interval of time, vibrating. I’ll look at those that the asteroid will reach the great one, the energy of the vibuhu viparous water of the ocean in the stroke of the blow, melting the bark, blowing it out of the air. Billiards of tons of spawned near melted specks-bags fell into the sea and for the next few days were buried in the siege balls of the seabed.
Behind the words of Heri Bayerli, exact date the fall of the asteroid was not visible, but having fallen on the deak, it rose from that month, when the stench showed caught the bags mountain breed And, maybe, near the water, not on land. Such vysnovki vcheniy zrobiv on pіdstavі vyvchennya warehouse sacks.
The mineral warehouse of the known bags does not correspond to that warehouse, which could be identified from the evaporation of continental measles, even if there is a lot of water that covers the surface of the Earth in the Danish period, it was less, lower, today. Bayerley, demonstrating a slab of gray stone, on a bulo one can see a ball of sacks that are intertwined with balls of dog or mule.
Falling asteroid called out to a giant tsunami
Behind the words of a vchenogo, a tsunami wind went around the whole earth in 30 years. Sweat water, mabut, crooked mustache, crim gir. Bayerley also pointing out those tsunami darling the majestic masses of the earth, sharply changing the coastlines of the continents. Teplova diya vibuhu boiled water in the oceans to a depth of 9 to 90 meters.
All or maybe all living organisms perished, for they lived on Earth or near the surface of the ocean. For more information about the great tsunami caused by the fall of asteroids, read the article "" from the cycle "Checking for the Day of Judgment".
Who was lucky to survive after vibuha asteroid?
Behind the words of the vchenih, the Earth already founded primitive, bacterial forms of life. І akscho falling asteroid It is close to 32 kilometers in diameter, and everything is on the surface of the Earth. The first hot steam and the melted rock of Mali would be the most detrimental to life, and the ruinous tsunami completed the catastrophe.
Because of this, the winter came incredibly cold, viklikana with particles of a saw, which roamed in the atmosphere, as if they crossed the dawn of the light of the Sun. Those living organisms, yakі lived, ymovіrno, lingered in the clay rocks below the Earth. . Such catastrophes, perhaps on such a scale, were experienced by the Earth in the last period. For example, one of the remaining podias is the comet's sway over the territory of the future Canada, becoming noticeable recently: less than 12,900 years ago. Such a legacy has evoked,.
Bayerli first showed evidence of the catastrophe in 1984, in 1984, if the ancient volcanoes in Australia and Pivdenniy Africa were victorious. Vin published his first work with problems in 1986 roci. At this time, it is customary to take into account that inner part The Sonyachna system suffered two aftermath of massive bombardment by asteroids or comets of a cryptic adventure. What threatens the Earth with the fall of an asteroid contagiously in the future? About tse.
Astronomers 5 spring of which year. We received yoga from the Catalina Sky Survey Observatory (Tucson, Arizona). Tse celestial body dosit nezvichne, yogo diameter becomes less than 7-16 meters. 7th spring of the vineyards for 40,000 kilometers from the Earth. In other words, astronomers knew about the date of 2016 RB1 only two days before the asteroid approached the Earth, and when the asteroid approached our planet at a minimum distance.
NASA's Near Earth Object Program is engaged in the development and classification of celestial bodies, thus making it unsafe for the Earth and all our civilizations. Ale, like a bachimo, this program does not help to reveal all the heavenly bodies close to the Earth, like to create a potential for us to be unsafe. Chi rich lost some objects? That y vzagali - naskolki asteroids are really unsafe, maybe y follow them not varto?
2016 RB1 zavdyaks to their sizes do not become especially unsafe. Navit yakbi vіn having fallen to the Earth, there would be no significant poshkodzhen. Narazi asteroid pishov to Venus. With it, you can get closer to the minimum distance from the future of 2017. Then, in 2020, the asteroids will again fall in order with the Earth. Ale already far away, lower than the last time. It seems to me that there is no particular concern - closed.
Spring 7 another asteroid approaching the Earth, rich in size, lower 2016 RB1. The diameter of this object (catalog number 2004 DQ41) is larger and becomes more than a kilometer. The minimum distance, as the asteroid approached our planet, was 15 million kilometers. There is not much to boast about in particular.
And we know that the Earth has repeatedly stumbled from the great celestial bodies at its past. One of these zіtknen became less than three years ago.
Todi, on February 15, 2013, having consumed a perceptibly small asteroid into the Earth’s atmosphere, which took the name “Meteorite Chelyabinsk”. The fall of that celestial body was accompanied by a series of atmospheric vibrations. Near the Chelyabinsk region, few fragments of an object were found from a salmon mass of 654 kg. According to the estimates of fahivtsiv, the object of the object is revisiting 4 billion years.
This asteroid, as if they were strengthening the veins, if they were a single whole with a larger celestial body. Ale, close to 300 million years ago, the wines were seen in the main body, after all, as if they were. The object was heated up to 650 degrees in the course of the trip. Kіlka tenskіv tysyach rokіv that asteroids, scho already vydkolovsya, zіtknuvsya with another celestial body, becoming smaller.
Yogo mass at the time of entry into the Earth's atmosphere was about 13,000 tons, the diameter was 20 meters. In the atmosphere of the Earth, the heavenly body roared, deyakі yogo ulamki reached the surface of the planet. All this caused a low ruin in the Chelyabinsk region. Buli and suffered, even though there were no casualties (want 1613 victims - a great figure). Ale yakbi asteroids were three times larger, the consequences of the fall of such a celestial body on Earth could be richly important.
In the past, our planet had a tendency to drop great asteroids, which more than once became the cause of cataclysms. The traces of the past have not been lost through those that the geological activity of the planet, erosion, volcanic activity have all been erased by the hour. Truth is, the “scars” of the hard flooring are low, which showed up, we can no longer smooth it out, but I won’t get worse. A lot of students are allowed to know that the Moon has settled down at the hour of the Earth’s shutdown with the largest celestial body. "Avaria" became approximately 4.53 billion years ago. In addition, in the period from 4.1 to 3.8 billion years ago, asteroids and comets often fell to Earth. On the Month of the last period, even good commemorations have been lost.
On Earth, so follow the same way, and not one. For example, the Arizona crater, which is 30 kilometers away from the Winslow site. The rosemary of the crater is already great. The diameter of yoga is 1219 meters, the depth is 229 meters. The edges of the crater rise 46 meters above the plain. This is one of the most well-groomed craters. Appearing visibly recently - only close to 50 thousand years ago. Vcheni vvazhayut, scho crater was made just before the hour of the fall of a 50-meter meteorite, which is important 300,000 tons and fly 45-60,000 km / year. Vibration pressure due to falling pressure of 8000 Tovstun-type atomic bombs. Yakby is such a meteorite that fell at once, the consequences of the fall were small and strong negative consequences for people.
Alas, nothing in the porivnyannі z tim, yakі bіdі і ruynuvannya іg bіg bіg bіg bіg bіg bіg at once podіyati asteroids, equal to the size of the celestial body, as it became the reason for the appearance of the Chicxulub crater on the Earth. This is an ancient impact crater with a diameter of approximately 180 km and a depth of 17-20 km (it is located on the edge of the cob clay). Know wines on the Yucatan Islands.
Vcheni vvazhayut that the crater was settled 65 million years ago, like the crade period. The diameter of the asteroid that hit the Earth is estimated at 10 kilometers. The energy of the fall added 100 teraton to the TNT equivalent. The consequences were catastrophic. Tse tsunami curls 50-100 meters, fire all over the Earth, activation of volcanoes. Vіdbulisya change the climate, similar to the nuclear winter. Deyakі fahivtsі admit that the asteroid became one of the reasons for the extinction of the dinosaurs. Others won't get along with them. Yak bi was not there, yakbi is like that giant asteroid having fallen to the Earth at once, then our civilization would have ceased to exist in the eyes of the ninth.
Asteroids, like passing in unsafe proximity to the Earth, are not such a rarity. From recent feasts, astronomers have learned how to detect asteroids before they pass through the earth, or fall on the surface. In 2008, such an asteroid was revealed earlier. Vin having taken the catalog number 2008 TC3. This is a small trick of the rock with a diameter of about 4 meters and a carload of 80 tons. A day later, after the object was detected, it entered the Earth's atmosphere and vibrated here near the Nubian Desert.
In five years, in 2014, the number of new manifestations of asteroids, which is direct to the Earth. The object of 2014 AA is about 2-4 meters deep into the Earth's atmosphere in 21 years after its manifestation. Falling into the ocean.
Caution and Caution Again
Vzagali, asteroids - part of the guests in the Moon-Earth system. One of the remaining great objects, asteroid 2004 BL86, was a manifestation of the world of the past. Tsya 300-meter skeleton passed 1.2 million kilometers in the direction of the Earth, two more distant, lower in the direction of us Moon. Behind the data of physicist Mark Boslough, asteroids with a diameter of 20 meters pass through the geostationary orbit of the skin two rocks. Analogous asteroids pass through the orbit of a month approximately once a day. 40-meter objects to pass the order from the Earth (on the line, approximately equal to the line from the Earth to the Moon)
Alan Harris, astronomer, astronomer, thinks that there are close to 200 million objects with a diameter of 6 meters and more with our ships. Tobto such objects can not be interrupted by a constant order from the Earth. Ale їх orbits pass in order, and early chi pіzno mi їх bachimo nearby. Harris states that about once every two rocks, objects with a diameter of 6 meters and more fall on the Earth.
To keep an eye on unsafe ships, NASA uses the Catalina Sky Survey system. All manifestations of objects, which can become unsafe for the Earth, are catalogued. In 1998, the US Congress entrusted NASA with the identification of at least 90% of the "susidiv" of the Earth with a diameter of 1 kilometer and more. In 2005, the Congress appointed NASA to inspect and asteroid, the expansion of which to become 140 meters and higher.
Not only NASA is behind the asteroids, it’s up to them to do it all at once report card orbits of potentially unsafe for the Earth celestial bodies from the report classification of these bodies. At the moment, there are more than 12,000 objects, of which 1% are comets, and reshta are asteroids. Deyakі їх already large, їх diameter becomes a kilometer and more. Rozmіr more - from 100 to 300 meters. Such asteroids can cause the greatest destruction of the Earth, similar to the effects of nuclear bombardment.
How many unsafe asteroids?
Even unsafe. The threat to walk around our nearest sucid-asteroids is entirely real. According to fahivtsiv estimates, asteroids, equal to the ruinous power of the Tunguska meteorite, fall to the Earth approximately once every 500 years. Asteroids, equal in size to the one that caused the destruction of the Arizona crater, appear on our planet once in a thousand years. And the giants, similar to an asteroid, having created the Chicxulub crater, fall once in a hundred million years. Alece statistics. A giant can fall to Earth like offensive rotation, i in 100 million years.
As already mentioned above, such giants - tse end of our civilization. Asteroids are less likely to become the cause of the strongest local ruins at the borders of one country. Ale, one can only guess about the traces of such ruins, as if asteroids could create a small space in the valley here near the densely populated industrial region.
12,000 asteroids close to the Earth - not all. Fakhіvtsіv are low at a thought, their number of things and can reach 200 thousand (diameter 100 meters and more). But the problem is that even asteroids with a diameter of less than 100 meters become a significant problem for people. Already a 25-meter object can become the cause of significant disruptions at the scale of the place and the movement. Everything that is bigger beyond the world is already a regional problem. Even more - global.
How to be greedy?
The main task of humankind at once is the folding of cards of potentially unsafe heavenly bodies. So far, NASA and other organizations are coping with this. Ale, the picture is still unclear. І navit zavdannya revealing 90% of potentially unsafe objects - far from everything that needs to be bred. Even if it’s from the asteroids, if it didn’t reach the number of quiet ones that they are afraid, it’s possible to approach the Earth with a majestic swedishness. At least 50% of the objects close to the Earth were discovered and cataloged in a wide range of hundreds of meters and more.
The work can be continued. And it is especially important that our system can have new, previously unknown objects. You can visit the asteroid belt or visit the Kuiper belt. And at the hmari Oort, behind the astronauts' assholes, there may be over 2 trillion comets. Perhaps, as one of them, we cannot imagine, has already entered the trajectory, how to bring you to the Earth? Everything can be.
The main threat is not the belt of asteroids, which is a blessing to do good, but the fortunes of distant regions of space, about which we still do not know anything. Threat - all small asteroids, yakі not vydstezhuyutsya. Go about the objects of the world around the Chelyabinsk meteorite. global problem stench is not є, but if such an asteroid falls here in a densely populated region, then one cannot be called a receiver of heritage. Moreover, it is possible to reveal them, then even at the last moment, without intermediary before the fall.
Asteroid threat to a large number of people seems insignificant and unrealistic. Really, everything is richer real, less important. Obviously, it doesn’t mean that it’s necessary to start experiencing some asteroids at once, zaroblyayuchi nervous vision. But to know that it is necessary to understand the problem.
At the same time, NASA launched OSIRIS-Rex, a probe that is responsible for the asteroid Bennu. Surrounding the celestial body, the probe is guilty of picking up the shards of the birth of that virus from tsimi zrazkami back to Earth. The turnaround time is 2023. Fahіvtsі NASA vavzhayut that this asteroid is one of the most unsafe living people celestial objects. At 2135 wines passed in total 300 thousand kilometers from the Earth.
The creation of an effective system for the detection of asteroids, the development of a security system - all that is necessary for humanity. To take care of this may not be taken by the country, but the whole world of light.
