1692 Subbotina, provisional designation 1936 QD, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 37 kilometers in diameter. It was discovered by Russian astronomer Grigory Neujmin at the Crimean Simeiz Observatory on 16 August 1936.[10] On the following night, astronomer Karl Reinmuth independently discovered the body at Heidelberg, Germany.[2]
The dark C-type asteroid is also classified as a Cg-subtype on the SMASS taxonomic scheme. It orbits the Sun at a distance of 2.4–3.2 AU once every 4 years and 8 months (1,699 days). Its orbit has an eccentricity of 0.14 and an inclination of 2°, nearly coplanar to the ecliptic.[1] The first used precovery was taken at Heidelberg Observatory in 1931, extending the asteroid's observation arc by 5 years prior to its discovery. However, the first observations were already made at the discovering observatory in 1927.[10]
A rotational light-curve was obtained from photometric observations made by Italian astronomer Silvano Casulli and French astronomer Laurent Bernasconi in October 2006. The light-curve gave a well-defined rotation period of 9.2457±0.0005 hours with a brightness variation of 0.3 in magnitude (U=3).[9]
According to the space-based surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 36.1 and 39.9 kilometers in diameter and its surface has a notably low albedo in the range of 0.034 to 0.049.[5][6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.04 and a diameter of 36.5 kilometers.[4]
The minor planet was named in memory of eminent Soviet scientist, Mikhail Fedorovich Subbotin (1893–1966), long-time director of the Institute of Theoretical Astronomy in former Leningrad. The lunar crater Subbotin was also named in his honour.[2][3] Naming citation was published before November 1977 (M.P.C. 2740).[11]
