1692 Subbotina, provisional designation 1936 QD, is a dark background asteroid from the central region of the asteroid belt, approximately 37 kilometers (23 miles) in diameter. The carbonaceous Cg-type asteroid has a rotation period of 9.2 hours.[12] It was discovered by Grigory Neujmin at the Crimean Simeiz Observatory in 1936, and later named after Soviet mathematician and astronomer Mikhail Subbotin.[1][2]
