asteroid impact near

Asteroid 2003 QQ47 could hit earth in March 21, 2014. This would be an extinction level event. The asteroid is 1.2 kilometers in size. The brilliant fireball would light up the sky. It would be not as bad as the one that destroyed the dinosaurs, but enough to collapse our civilization. The impact site on land would have a hole bigger than meteor crater, or if it hit our oceans a giant tsunami would smash coastal cities leaving a trail of devastation.
