Recent research has shed light on the origin of most meteorites that fall on Earth. Scientists have identified three young asteroid families in the main asteroid belt as the source of 70% of our planet's meteorites. The Karin, Koronis, and Massalia families are responsible for the vast majority of meteorite arrivals, with the Massalia family accounting for 37%. Until now, only a small fraction of meteorites had been linked to specific sources, leaving the origin of most remains a mystery.
