Thanks to dozens of video reports, scientists are getting a pretty good handle on the life history of the massive meteorite that exploded above Russia earlier this month. They know it is rocky and a common type, and now they know where it probably came from. Scientists are scrambling to publish papers describing its origins in the middle of the solar system.
The asteroid chip that became the recent meteorite came from a spot in the asteroid belt near Jupiter, about 2.5 times further from the sun than Earth is, according to NASA.
