    1692 Subbotina, provisional designation 1936 QD, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 37 kilometers in diameter. It was discovered by Russian astronomer Grigory Neujmin at the Crimean Simeiz Observatory on 16 August 1936.[10] Astronomer Karl Reinmuth in Heidelberg, Germany independently discovered the body on the following night.[2]

    The asteroid orbits the Sun at a distance of 2.4–3.2 AU once every 4 years and 8 months (1,699 days). Its orbit shows an eccentricity of 0.14 and is nearly coplanar to the ecliptic, tilted by only 2 degrees. Light-curve observations carried out by Italian astronomer Silvano Casulli and French astronomer Laurent Bernasconi gave a well-defined rotation period of 9.246 hours with an amplitude of 0.3 in magnitude.[4][9]

    The carbonaceous C-type asteroid, classified as a rare Cg-subtype in the SMASS classification scheme, has a notably low geometric albedo of around 0.04, determined by the space-based missions IRAS, Akari, WISE and NEOWISE.[5][6][7][8]

    The minor planet was named in honor of eminent Soviet scientist, Mikhail Fedorovich Subbotin (1893–1966), long-time director of the Institute of Theoretical Astronomy in former Leningrad.[2] The lunar crater Subbotin was also named in his honour.[3]
