1783 Albitskij, provisional designation 1935 FJ, is a carbonaceous asteroid from the middle region of the asteroid belt, about 21 kilometers in diameter. It was discovered on 24 March 1935, by Soviet–Russian astronomer Grigory Neujmin at Simeiz Observatory (Симеиз) on the Crimean peninsula.[9]
The dark C-type asteroid – classified as a Ch-subtype in the SMASS taxonomic scheme – orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,587 days). Its orbit is tilted by 12 degrees to the plane of the ecliptic and shows an eccentricity of 0.13. It has a rotation period of 12 hours[8] and an albedo in the range of 0.05–0.07, according to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the U.S. Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5][6][7]
The asteroid is a member of the Eunomia family, a large group of stony S-type asteroids and the most prominent family in the intermediate main-belt. Since the asteroid's spectral type is that of a carbonaceous C-type, rather than of a stony S-type body, it is considered to be an interloper.[10]
It is named after Soviet astronomer and head of Simeiz Observatory, Vladimir Albitzky (1891–1952). He is well known for his research on radial velocities and variable stars, as well as for his discoveries of ten asteroids. He was also the head of the Simeis department of the Pulkovo Observatory from 1934 onward.[2]
