Q & A
1 where meteorites come from?
Cook, chief scientist of NASA's Marshall Space Flight Center Meteoroid Environment Office, that this meteorite from the asteroid belt, about a year ago after entering the Earth's atmosphere more than 30 seconds after a violent explosion and fragmentation.
2 how often "hit the ground" ?
Cook said, very common small meteoroids from comets or asteroids colliding with Earth, the Earth daily will intercept 80 tons of space material, car-sized objects fall into the Earth's frequency is about once a month. University of Michigan professor of astronomy Birkin, the space stones so big like Russia meteorite hit the Earth probability every five years to 30 years.
3 Near-Earth asteroids?
NASA, Russian meteorite orbit asteroid 2012DA14 significantly different. Preliminary analysis indicates that the meteorite from north to south movement opposite asteroid 2012DA14 track, from south to north.
4 Why did not advance observation?
U.S. weather satellite only took a snapshot in this meteorite subduction process, while global asteroid observation telescope network did not detect the meteorite. Birkin explained telescope and global coverage. , Similar to such celestial bodies in the areas covered by the telescope with the current telescope is difficult to see this telescope is mainly used to observe the larger body.
5 humans can withstand asteroid it?
Pukhov, Director of the Russia's strategic and technical analysis center, said there was still no country can really solve the problems of the asteroid threat to Earth. Even if the future use of certain systems can achieve intercept, will not be a large number of applications, because the cost is very expensive. Some countries, including Russia, has a system to track the asteroid, but not advanced enough. Russia's "national defense" magazine editor  said Russian-US state-of-the-art air defense and missile defense system can not detect the asteroid threat, the only high-power radar systems to monitor near-Earth space.
