Collision with an asteroid threatens Earth in February 2013. If the asteroid 2012 DA14, open a few days ago, not razminetsya with our planet, the scale of the disaster will be comparable to the fall Tung0usskogo meteorite, scientists warn.
Asteroid 2012 DA14 found February 23 employees of Spanish La Sagra Observatory. Then, these data confirmed the French, Italian and American scientists. According to their calculations, the orbit of an asteroid with a diameter of 40 to 95 m, intersect the earth. As astronomers have calculated, February 15, 2013 the asteroid will fly only 26,9 thousand miles away from our planet, which is below the orbits of geostationary satellites.
The official said the Pulkovo Observatory Victor Lvov, 2012 relates to the DA14 kvazisputnikam Earth — asteroids that periodically come closer to our planet, then behind, then ahead of her. "These are objects that are from time to time moving around the earth. In fact, they do not go around the earth, but in a coordinate system with two centers — the Sun and the Earth — it will be like a circle around the earth "- quoted scientist RIA" Novosti ".
Now, as the Lions, you can not accurately predict whether the encounter with the Earth in 2012 DA14. "We should follow him, he can be as far from the Earth, and to get close, including, so far as to fall to Earth. There is some probability that he will face with the Earth. The only way for us — is to gain observations, new observations allow us to clarify the orbital data and accurately learn the fate of this object, "- said the scientist. Although the fall of 2012 and the DA14 will not lead to the death of all life, the scale can be compared to the Tunguska catastrophe in 1908, he added.
If DA14 razminetsya with Earth, the next time he gets close to the planet any time soon. It is estimated that in 2056 he will approach Earth at a distance of about 1.1 million km, and in 2089 — at a distance of 3.5 million kilometers. "More close encounters in this century not" — said the scientist.
According to the calculations of astronomers, large asteroids fall to Earth on average once every 100 thousand years. In extreme cases, they may be a threat to the existence of life on our planet, as it was during the mass extinction of dinosaurs 65 million years ago. The greatest concern is the asteroid Apophis, which can run into the ground in 2036. Celestial body comes closer to our planet April 13, 2029 at a distance of 37-38 thousand kilometers. But even after 7 years, April 13, 2036, Apophis will approach the Earth at a dangerous distance, which can bump into it. It is true that the probability of this is negligible.
