A few days ago- on February 23, 2012 was opened a new asteroid 2012 DA14, which, according to specialists of NASA- on February 15, 2013 will fly at a very short distance from the Earth - only 27,000 kilometers (see the photo of NASA website at the top of this article). According to scientists, asteroid 2012 DA14 has a length of 100 meters and in the case of hitting the Earth, can be released the energy, which equivalent to the explosion of the hydrogen bomb. On February 15, 2013 will be the first recorded case in which an asteroid can fly at a small distance from the Earth, we note, that the asteroid 2005 YU55, which caused the attention of scientists in November 2011, flew at a distance of 325 000 kilometers from Earth, more than 10 times higher, than the distance of the asteroid 2012 DA14, so some scientists do not rule out a collision the Earth with asteroid, because 27,000 kilometers - the distance, that may be in the range of errors of astronomical calculations, and this short distance is actually evidence of real probability of a collision, so other planets of the Solar system can change the trajectory of this asteroid.
