Its characteristics may help to explain certain discrepancies in the classification of near-Earth asteroids. When the Chelyabinsk fireball exploded over the Russian sky in 2013, it left a rather rare sort of meteorite on Earth. What distinguishes the Chelyabinsk meteorites and others like them is t

Battle, Reddy, and their colleagues collected data on the surface composition of 1998 OR2 using the RAPTORS system, a telescope atop the Kuiper Space Sciences building on campus, and determined that it appeared like an ordinary chondrite asteroid. Chondrite asteroids have a lighter appearance and contain the minerals olivine and pyroxene.
“The mismatch was one of the early things that got the project going to investigate potential causes for the discrepancy,” Battle said. “The asteroid is not a mixture of ordinary chondrite and carbonaceous asteroids, but rather it is definitely an ordinary chondrite, based on its mineralogy, which has been altered – likely through the shock darkening process – to look like a carbonaceous asteroid to the classification tool.
