Asteroid Belt As Meteorite Source

[Steve Herschbach]

"Ancient collisions in the solar system’s asteroid belt - not space rocks passing near our planet - are the source of many meteorites found on Earth, according to new research."

"Most meteorites that fall today are H and L type ordinary chondrites, yet the main belt asteroids best positioned to deliver meteorites are LL chondrites. This suggests that the current meteorite flux is dominated by fragments from recent asteroid breakup events and therefore is not representative over longer (100-Myr) timescales."
