Astronomers from Colombia have traced the origin of a meteor that injured about 1,000 people after breaking up over central Russia earlier this month.Using amateur video footage, they were able to plot the meteor's trajectory through Earth's atmosphere and then reconstruct its orbit around the Sun.
The meteor that exploded over Russia Friday was slightly larger than previously thought and more powerful, too, NASA scientists say. The explosion over the city of Chelyabinsk, on Friday injured more than 1,000 people and blew out windows across the region in a massive blast captured on cameras by frightened witnesses.
