The Sikhote-Alin shower was the largest recorded witnessed meteorite fall in history. Like ordinary chondrites, carbonaceous chondrites can be more minutely classified based on their mineral composition. If this is the case, they could tell us a lot about the formation of Earth and other terrestrial planets.
