2011 Veteraniya, provisional designation1970 QB1, is a stony Vestianasteroid from the inner regions of theasteroid belt, approximately 6 kilometers in diameter. It was discovered on 30 August 1970, by Soviet astronomerTamara Smirnova at theCrimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula, and named for the Sovietveterans of the Second World War.[2][7]
Veteraniya is a member of theVesta family. It orbits the Sun in theinner main-belt at a distance of 2.0–2.7 AU once every 3 years and 8 months (1,347 days). Its orbit has aneccentricity of 0.15 and aninclination of 6° with respect to theecliptic.[1] The firstprecovery was taken atPalomar Observatory in 1950, extending the asteroid'sobservation arc by 20 years prior to its discovery.[7]
TheCollaborative Asteroid Lightcurve Link (CALL) andPan-STARRS' large-scale survey classify it as aS-type andV-type asteroid, respectively.[3][6]
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer, the asteroid's surface has an exceptionally high albedo of 0.46 and a corresponding diameter of 5.2 kilometers,[4] while CALL assumes a standard albedo for stony asteroids of 0.20. CALL therefore calculates a larger diameter of 7.8 kilometers, as the lower the albedo (reflectivity), the higher the body's diameter at a constant absolute magnitude (brightness).[3]
A photometriclightcurve analysis by Japanese astronomer Sunao Hasegawa in 2004 has given arotation period of8.209±0.005 hours with a brightness amplitude of0.30 inmagnitude.[a]
Thisminor planet was named in honor of the Sovietveterans of theGreat Patriotic War.[2] (The term is used in Russia to describe the conflict fought between the Soviet Union and Nazi Germany on the Eastern Front of World War II during 1941–1945.) The officialnaming citation was published by theMinor Planet Center on 1 September 1978 (M.P.C. 4481).[8]
