Apocalypses, predicted by different experts are different, reports Rus.Media. There is a whole classification that at different times can threaten our planet. For example, should pay attention to the stone Apocalypses – that is, parts of the world due to a collision with some rock – an asteroid, comet or other celestial body, respectively, which at least partially solid structure.

Basically, the experts say about the possible impact on our planet is asteroids simply because they are informed with high probability have led to any serious consequences. For example, for the fall of one such stone, probably could have gone the dinosaurs. That is, to a large extent changed the biosphere of our planet. Of the latter, it is worth remembering Chelyabinsk meteorite. He of all people, as can be understood, not destroyed, however, destruction was relatively large. Stone, in this case, was not so great.

In fact, for some time, some experts say the threat 12 Oct – asteroid 2012 TC4, which is larger than the Chelyabinsk meteorite twice. While he has a speed of 28 kilometers per hour, and that 12 he will fly close to Earth at a distance of only about 50 thousand kilometers. This is less than how much of the planet’s natural satellite, at seven-eighths. The absolute probability that an object will enter the atmosphere. However, some experts recommend that people, that is to say, to keep in mind. It is possible that the crash still happens. American aerospace Agency NASA, however, altogether exclude the possibility of such a threat. They say that, on the contrary, 2012 TC4 is a very interesting stone in order to test the system to protect the Earth from the stone of the Apocalypse.

According to Paul Chodas, head of the research center of near-earth objects, the Agency knew that the asteroid is very close. So last year in 2012 TC4 decided to work out what would happen if the stone still collided with the planet and how to avoid it – yet at least in theory.

Chodas noted that in General, the asteroids reach the Earth almost every day, but most of them are small, they mostly just burn up in the atmosphere. There are more, but those that do not approach the planet at a dangerous distance. NASA knew that 2012 TC4 will be closer to Earth than the Moon, although exact numbers are calculated not so long ago. However, it still would be a great option to investigate. So far, the Ministry mainly deals with tracking the orbit of the asteroid. A work in progress since the beginning of August. Also wondering what exactly the stone size and density. Investigate it in brightness and optical wavelengths, and the reflectivity. Than the asteroid darker, so it lower the density. Importantly, what is stone weight, since this will make it clear the damage that could be inflicted in the fall. According to Paul Chodas, if 2012 really TC4 collided with the Ground, it would be difficult to predict the full consequences. Here still depends on the trajectory of flight, which is currently estimated. The exact coordinates of where you would have fallen asteroid, Chodas reported, noting that there are plus or minus more than a dozen miles away, so the calculations are very complicated, hypothetical main point currently specified.

To reject the asteroid, you have to find it. At least three years, and preferably for five. In this case, it needs to cooperate all the space agencies without exception. How to deflect the asteroid and not to allow it to collide with Earth? According to Paul Chodas, it is easiest to push it with a very large spacecraft. If you run the latter at a high enough rate, then it will take momentum to the asteroid, and the somewhat slow down. In the case of approaching a large stone recommended the involvement of any gravitational forces. That is to release in the direction from the Earth another asteroid to the one she faces, simply “pulled”. But to do this it is necessary in advance for a year or two. Or a third option – to shoot the asteroid ion beams at high speed. If a lot of time to perform, the hypothetical celestial stone indeed rejected. Those methods that are most promising. In fact, after a span of 12 Oct 2012 TC4 might come close to Earth in the year 2050, however, the probability of such less than fifty percent. Chodas noticed that, most likely, the asteroid’s orbit will still be much further, so that this stone will not threaten the Earth for many years.

At the same time the American space Agency is searching for and other objects that could potentially collide with the planet. Of course, much easier to find larger, from several hundred meters to one kilometer. Paul Chodas assured that their orbits are precisely known, of course, where they fly, and such stones are precisely of the Earth is not threatened. However, about smaller definitely is difficult to say. In particular, confidence in the fact that once, in the coming years, the planet will encounter some 15-meter stone, not available. However, the work continues to be conducted, and, most likely, in the future, the approach of these asteroids will be able also to know in advance to use, in which case (and with appropriate technical means), of the above-mentioned methods.
