1283 Komsomolia (prov. designation:1925 SC) is a metallicbackground asteroid and potentiallyslow rotator from the outer regions of theasteroid belt. Discovered byVladimir Albitsky in 1925, it was later named afterKomsomol, a political youth organization of the former Soviet Union. TheM-type asteroid has roughly arotation period 96 hours of and measures approximately 30 kilometers (19 miles) in diameter.
Komsomolia was discovered on 25 September 1925, by Soviet astronomerVladimir Albitsky at theSimeiz Observatory on the Crimean peninsula.[3] It was independently discovered by German astronomerKarl Reinmuth atHeidelberg Observatory on 10 October 1925.[2] Only the first discoverer is officially recognized.[2] The asteroid was first observed asA902 TE at Heidelberg in October 1902.[3]
Komsomolia is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements.[4] It orbits the Sun in theouter main-belt at a distance of 2.5–3.9 AU once every 5 years and 8 months (2,075 days). Its orbit has aneccentricity of 0.22 and aninclination of 9° with respect to theecliptic.[1] The body'sobservation arc begins at Heidelberg in October 1902, almost 23 years prior to its official discovery observation.[3]
Thisminor planet was named afterKomsomol ("All-Union Leninist Young Communist League"), the youth wing of theCommunist Party of the Soviet Union (CPSU).[2] The officialnaming citation was published by theMinor Planet Center in November 1952 (M.P.C. 838).[13]
Komsomolia has been characterized as a metallicM-type asteroid by theWide-field Infrared Survey Explorer (WISE).[7] The Asteroid Lightcurve Database assumes it to be a carbonaceousC-type asteroid.[5]
In December 2006, a fragmentary rotationallightcurve ofKomsomolia was obtained from photometric observations by French amateur astronomerPierre Antonini. Lightcurve analysis gave arotation period of 96 hours with a brightness amplitude of 1.03magnitude (U=1+).[11]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA's WISE telescope,Komsomolia measures between 26.87 and 36.09 kilometers in diameter and its surface has analbedo between 0.071 and 0.1856.[6][7][8][9][10] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.1703 and a diameter of 26.78 kilometers based on anabsolute magnitude of 10.4.[5]
