That means that before it shattered windows in the city of Chelyabinsk and turned people around the world into gawkers fascinated by a calamity — and by the amazing video footage of it — the meteor spent billions of years traveling through space.
When it detonated over Russia, the explosion was powerful enough to be "detected by 17 nuclear monitoring stations around the globe," as The Christian Science Monitor reports.
The meteor, which may have weighed as much as 10,000 tons and measured about 55 feet across, was traveling at an estimated 11 miles per second when it reached Earth, according to a report at io9.
