The carbonaceous Cg-type asteroid has a rotation period of 9.2 hours. It was discovered by Grigory Neujmin at the Crimean Simeiz Observatory in 1936, and later named after Soviet mathematician and astronomer Mikhail Subbotin. Discovery Subbotina was discovered by Soviet-Russian astronomer Grigory Neujmin at the Crimean Simeiz Observatory on 16 August 1936. On the following night, astronomer Karl Reinmuth independently discovered the body at the Heidelberg Observatory in Germany. The asteroid was first observed as 1927 SL at the discovering observatory in September 1927. Its first used observation was made at Heidelberg in July 1931, extending the body's observation arc by 5 years prior to its official discovery observation in 1936. Naming This minor planet was named in memory of eminent Soviet mathematician and astronomer, Mikhail Subbotin (1893–1966), long-time director of the Institute of Theoretical Astronomy (ITA) in former Leningrad. The lunar crater Subbotin was also named in his honour. The official 1692 naming citation was published by the Minor Planet Center on 1 June 1967 (M.P.C. 2740). Orbit and classification Subbotina is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 2.4–3.2 AU once every 4 years and 8 months (1,700 days; semi-major axis of 2.79 AU). Its orbit has an eccentricity of 0.14 and an inclination of 2° with respect to the ecliptic. Physical characteristics In the SMASS-II taxonomy, Subbotina has been characterized as a dark Cg-type, a subtype of the wider group of carbonaceous C-type asteroids with low albedos. Rotation period In October 2006, a rotational lightcurve of Subbotina was obtained from photometric observations by Italian Silvano Casulli and French Laurent Bernasconi, both amateur astronomers. Lightcurve analysis gave a well-defined rotation period of 9.2457 0.0005 hours with a brightness variation of 0.3 in magnitude (U=3). Somewhat higher amplitudes of 0.42 and 0.62 magnitude were found by the NEOWISE mission. Diameter and albedo 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, Subbotina measures between 34.8 and 43.0 kilometers in diameter and its surface has a notably low albedo in the range of 0.02 to 0.049. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.04 and a diameter of 36.5 kilometers with an absolute magnitude of 11.3. References 30em 2018-06-24 last obs.
