Most Pristine Meteorites Known
The Yukon meteor fragments were identified as carbonaceous chondrites, the most pristine, organically rich meteorites known. Carbonaceous chondrites are rare and difficult to recover because they are so fragile, easily breaking down during entry into Earth's atmosphere and during weathering on the ground. They comprise only about 2 percent of all meteorites known to have fallen to Earth.
