985 Rosina, provisional designation 1922 MO, is a stony asteroid and sizable Mars-crosser on an eccentric orbit from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 14 October 1922, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany.[3] The asteroid's name is a common German female name, unrelated to the discoverer's contemporaries.[2]
