U.S. astronomers have completed work on the identification of many of the large asteroids that may pose a threat to the planet Earth. Just found them more than 700 of the approximately 1.1 thousand potentially dangerous.
Now experts are considering developing a system that would not pinpoint such large celestial bodies, the collision which can, for example, to destroy a small town. This was reported by astronomers, speaking before the Senate Subcommittee on Science, Technology and Space.
As informs "Interfax", the work on the identification of potentially hazardous asteroids was launched in 1998 and completed In 2008, the representative of the National Aeronautics and Space Administration (NASA) Lindley Johnson.
In September last year, astronomers discovered a large asteroid, which, in their opinion, March 21, 2014 was to collide with the Earth, that would cause effects comparable to the explosion of 20 million atomic bombs. Soon, however, the calculations have been revised, and the researchers concluded that this deadly celestial body passes by the planet.
