Meteor that hit Russia may have had close shave with Sun
Paris (AFP) Aug 26, 2013
The meteor that injured over 1,500 people when it exploded and showered debris over Russia in February may have had a close shave with the Sun earlier, researchers said Tuesday. A study of its composition showed the space rock had undergone "intensive melting" before entering Earth's atmosphere and streaking over the central Russia's Chelyabinsk region in a blinding fireball, they said in a statement. This "almost certainly" points to a near-miss with the Sun, or a collision with another body in ... read more
