Modern equipment can not track the movement of small celestial bodies.
Russian scientists said that modern technology can prevent a collision with Earth asteroids such as the Chelyabinsk meteorite. According to experts, you need to pay more attention to minimize the negative impact from falling bodies in space. it requires a system of detection and warning of space threats directly in the space, experts believe.
This statement was made by representatives of the all-Russian research Institute on problems of civil defense and emergency situations of EMERCOM of Russia, Institute of astronomy and Institute of Geosphere dynamics RAS. The scientists noted that the smaller the size of the cosmic body, the harder it is to notice. For example, the Chelyabinsk meteorite, the diameter of which ranged from 16 to 19 meters, it was impossible to detect under any circumstances.
Small meteors cannot be committed at a great distance because of the limitations of the penetrating power of survey telescopes. But for short distances it is difficult to find a small body due to its high travel speeds and small residence time in the atmosphere.
At the same time, scientists stressed that there are 15 thousand celestial bodies flying to the Ground with a pre-calculated trajectory. They put on a special account and are constantly under the supervision of the art equipment, RIA Novosti reported.
