10711 Pskov, provisional designation1982 TT2, is a darkasteroid from the middle region of theasteroid belt, approximately 13 kilometers in diameter. It was discovered on 15 October 1982, by Soviet astronomerLyudmila Zhuravleva at theCrimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula, and later named for the Russian city ofPskov.[2][4]
Pskov orbits the Sun in thecentral main-belt at a distance of 2.1–3.3 AU once every 4 years and 6 months (1,657 days). Its orbit has aneccentricity of 0.22 and aninclination of 12° with respect to theecliptic.[1] The body'sobservation arc begins 27 years prior to its official discovery observation, with aprecovery taken atPalomar Observatory in November 1955.[4]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Pskov measures 13.01 kilometers in diameter, and its surface has analbedo of 0.076, which is rather typical for a carbonaceousC-type asteroid of the main-belt.[3]
As of 2017,Pskov'srotation period, composition and shape remain unknown.[1][5]
Thisminor planet was named in honor of the old Russian city ofPskov, located near the border to Estonia, whereVelikaya River entersLake Peipus (Pskov lake). The city was first mentioned in the 10th century, and is now an administrative, industrial and cultural center.[2] The official naming citation was published by theMinor Planet Center on 24 July 2002 (M.P.C. 46102).[6]
