Asteroid to hit Earth soon

Recently, Spanish researchers have discovered a boulder. The 45-meter races at the small asteroid to Earth - and the calculations of astronomers suggest that close by her. Mid-February 2013 passed the asteroid with the name "DA 14" the blue planet and will approach it according to calculations by NASA to around 21 000 kilometers. The distance is less than some satellites - but the floor is not so dangerous.

The next killer asteroid to come - the only question is when. Then, astronomers know at least a statistical answer, and they have also developed scenarios that show what happens during a strike. Meets about an interplanetary potato size of 50 by 100 meters to our planet, it releases enough energy is released as a hydrogen bomb with an explosive force of 50 million tons of TNT. This corresponds, as the Swiss astronomer calculated Roland Brodbeck, a sphere of about 400 feet in diameter made ​​of pure dynamite. A pressure wave spreads out and rolled within 25 kilometers down everything you stand in your way
