1783 Albitskij, provisional designation 1935 FJ, is a carbonaceous Eunomian asteroid from the middle region of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 24 March 1935, by Soviet–Russian astronomer Grigory Neujmin at Simeiz Observatory on the Crimean peninsula.
The 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 has an eccentricity of 0.13 and an inclination of 12° with respect to the ecliptic. In 1933, it was first identified as 1933 TB at the U.S. Oak Ridge Observatory in Massachusetts, two years prior to its discovery. The body's observation arc begins one month after its official discovery with the first used observation made at Uccle Observatory in Belgium.
The asteroid is a member of the Eunomia family, a large group of typically stony S-type asteroids and a 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 (see Eunomia family § Interlopers).
According to the 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 21.4 and 25.6 kilometers in diameter and its surface has an albedo between 0.03 and 0.07. The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS and derives an albedo of 0.07 and a diameter of 21.3 kilometers, based on an absolute magnitude of 11.85.
Published by Cláudia Angeli and Maria A. Barucci, a rotational light-curve was obtained for this asteroid from photometric observations made at the French Haute-Provence and Pic du Midi observatories by astronomers at Meudon in the early 1990s. It gave a rotation period of 12 hours with a brightness amplitude of 0.4 magnitude (U=2).
The minor planet is named after Soviet astronomer, discoverer of minor planets and head of Simeiz Observatory, Vladimir Albitzky (1891–1952). His research included variable stars and the measurement of radial velocities. Naming citation was published on 1 June 1980 (M.P.C. 5357).
