Meteor that hit Russia came from Apollo asteroid family
The meteor that recently broke up over Chelyabinsk, Russia came from the Apollo class of near-Earth asteroids, researchers from the University of Antioquia in Colombia say. At 55-foot wide, scientists say the meteor was too small to be detected by sky surveys and its approach would have been blocked by the sun. Before the meteor hit, a NASA group led by Lindley Johnson had been recommending the setup of an international asteroid-warning network to watch for more near-Earth objects.
