A blazing meteor streaked across the skies of Russia on Thursday, leaving a large smoke trail in its wake before blowing up over the remote town of Chelyabinsk in the Ural mountains. More than 1,000 people reported injuries, and windows across the region were shattered by a deafening sonic boom. On Friday, a 150-foot-wide asteroid named 2012 DA14 whizzed by the Earth with just over 17,000 miles of separation to spare. That makes it the closest approach ever to the planet for a space rock of that size.
Chelyabinsk wasn't the only fireball reported on the same day that DA14 passed by. I don't know if I believe Frank Davis that most of them actually were related to DA14 in some way, but he has a couple possible explanations for the different trajectories. And these are supported by his computer models. If there's a chance that he's right it means that near-miss asteroids can be accompanied by such events -- meaning a serious risk when Apophis passes in 2029. If he's wrong, I'd like to see NASA or someone specifically debunk his models.
