Study Reveals Origins of 70% of Earth's Meteorites

Most meteorites are traced back to three asteroid families in the main asteroid belt, according to new research.

Researchers have identified that 70% of meteorites that strike Earth originate from three asteroid families: Karin, Koronis, and Massalia.
These findings are based on studies that analyzed the composition of meteorites and asteroids within the solar system's main asteroid belt.
The Massalia family, formed about 40 million years ago, is linked to a significant portion of L chondrite meteorites found on Earth.
The Karin and Koronis families, formed 5.8 and 7.6 million years ago respectively, are associated with H chondrites, another major class of meteorites.
This research marks a significant leap in understanding meteorite origins, increasing the traceable percentage from 6% to 70%.
