MOSCOW, 11 Oct — RIA Novosti. Falling of asteroids does not threaten life on Earth in the closest hundreds of years, the director of institute of astronomy of RAS (INASAN) Dmitry Bisikalo.© Illyustration of RIA Novosti considers. Depositphotos/1xpert, Depositphotos/SergeyNivens time Paradoxes: holes are found in the universe "Today about 19 thousand asteroids which can approach Earth orbit are revealed. For each known object the orbit and probability of collision more than for 100 years in the future pays off. Every day the new asteroids approaching Earth for these asteroids open orbits are defined and specified and probabilities of collision with planets pay off. Thus, almost all large near-earth asteroids more than 1 kilometer in size capable to cause global disaster on Earth, are known to astronomers. Results of mathematical modeling of the movement of the known large asteroids show that in the closest hundreds of years collision with these objects does not threaten Earth" — Bisikalo in an interview of RIA Novosti told. He noted that astronomers know about asteroids less than one kilometer in size because of a large number of such space bodies less. From near-earth asteroids from 100 meters in size no more than 10%, and 20-30 meters in size — about 1-2% are known to scientists. "For example, the recent Chelyabinsk meteorite was the size just about 20-30 meters. If the tilt angle at its falling was a little another, it could lead to serious regional accident. So the asteroid and cometary danger is a real threat which studying will help to avoid the victims and serious damage" — Bisikalo added.
