Meteorite source in asteroid belt not a single debris field![]() Mountain View CA (SPX) Feb 18, 2019 A new study published online in Meteoritics and Planetary Science finds that our most common meteorites, those known as L chondrites, come from at least two different debris fields in the asteroid belt. The belt contains many debris fields created from former dwarf planets, or dwarf planets in the making, that collided long ago. These fragments, called asteroids, continue to collide, producing the meteorites that fall to Earth today. "When meteorites fell near Creston, California on October ... read more |
