2959 Scholl, provisional designation1983 RE2, is a carbonaceousHildianasteroid from the outer regions of theasteroid belt, approximately 34 kilometers in diameter. It was discovered on 4 September 1983 by English-American astronomerEdward Bowell of theLowell Observatory atAnderson Mesa Station near Flagstaff, Arizona.[10] The asteroid was named after German astronomerHans Scholl.[2]
Scholl is a member of theHilda family, a large group that orbits inresonance with the gas giant Jupiter and are thought to originate from theKuiper belt.Scholl orbits the Sun at a distance of 2.9–5.0 AU once every 7 years and 10 months (2,861 days). Its orbit has aneccentricity of 0.27 and aninclination of 5° with respect to theecliptic.[1] On 23 October 1963, the asteroid was first identified as1968 UB3 atCrimea–Nauchnij, extending the body'sobservation arc by 20 years prior to its official discovery observation at Flagstaff.[10]
Scholl is an assumed carbonaceousC-type asteroid.[3]
A rotationallightcurve ofScholl was obtained from photometric observations by Swedish, Spanish, Italian and German astronomers. Published in 1998, the fragmentary lightcurve gave arotation period of 16 hours with a brightness amplitude of 0.14magnitude (U=1).[8]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Scholl measures between 32.783 and 45.60 kilometers in diameter and its surface has analbedo between 0.04 and 0.054.[4][5][6][7]
TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.055 and a diameter of 34.15 kilometers based on anabsolute magnitude of 11.1.[3]
Thisminor planet was named in honor of German astronomerHans Scholl (born 1942), who worked at theAstronomical Calculation Institute, Heidelberg, andCôte d'Azur Observatory in Nice, France. He is a co-discoverer of many minor planets and threemoons of Uranus.[2]
The official naming citation was published by theMinor Planet Center on 15 May 1984 (M.P.C. 8802).[11]
