1783 Albitskij, provisional designation1935 FJ, is a carbonaceous Adeonianasteroid from the middle region of theasteroid belt, approximately 22 kilometers in diameter. It was discovered on 24 March 1935, by Georgian–Russian astronomerGrigory Neujmin at theSimeiz Observatory on the Crimean peninsula.[13] The asteroid was named after Soviet astronomerVladimir Albitzky.[2]
Albitskij is a member of theAdeona family (505),[4] a largefamily of carbonaceous asteroids, when applying theHierarchical Clustering Method to itsproper orbital elements. It has also been dynamically classified as a member of theEunomia family (as many other members of the Adeona family), which can be ruled out, due to the fact, that this family consist of stony rather than carbonaceous asteroid.[3][14]: 23
The asteroid orbits the Sun in thecentral main belt at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,587 days). Its orbit has aneccentricity of 0.13 and aninclination of 12° with respect to theecliptic.[1]
In 1933, it was first identified as1933 TB at the U.S.Oak Ridge Observatory in Massachusetts, two years prior to its discovery. The body'sobservation arc begins one month after its official discovery with the first used observation made atUccle Observatory in Belgium.[13]
In theSMASS taxonomic scheme,Albitskij is a Ch-subtype, a hydratedC-type asteroid.[1] It has also been characterized as a common carbonaceous C-type byPan-STARRS photometric survey.[12] This agrees with the overallspectral type of the Adeona family (505).[14]: 23
Published by Cláudia Angeli andMaria Barucci, a rotationallightcurve was obtained for this asteroid from photometric observations made at the FrenchHaute-Provence andPic du Midi observatories by astronomers atMeudon in the early 1990s. It gave arotation period of 12 hours with a brightness amplitude of 0.4magnitude (U=2).[11]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Albitskij measures between 20.47 and 25.6 kilometers in diameter and its surface has analbedo between 0.03 and 0.07.[5][6][7][8][9][10]
TheCollaborative 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 anabsolute magnitude of 11.85.[3]
Thisminor planet is named after Soviet astronomer,discoverer of minor planets and head of Simeiz Observatory,Vladimir Albitzky (1891–1952). His research includedvariable stars and the measurement ofradial velocities.[2] The official naming citation was published by theMinor Planet Center on 1 June 1980 (M.P.C. 5357).[15]
