2985 Shakespeare (prov. designation:1983 TV1) is a stony Koronianasteroid from the outer region of theasteroid belt. It was discovered on 12 October 1983, by American astronomerEdward Bowell at Lowell'sAnderson Mesa Station near Flagstaff, Arizona, and later named afterWilliam Shakespeare.[2][9] The presumedS-type asteroid has arotation period of 6.1 hours and measures approximately 10 kilometers (6.2 miles) in diameter.
TheS-type asteroid is a member of theKoronis family, a group consisting of about 200 known bodies. It orbits the Sun in theouter main-belt at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,756 days). Its orbit has aneccentricity of 0.05 and aninclination of 3° with respect to theecliptic.[1] It was first identified as1962 JJ atGoethe Link Observatory in 1962. The body'sobservation arc begins with its identification1976 GV atCrimea–Nauchnij, 7 years prior to its official discovery observation at Anderson Mesa.[9]
Thisminor planet was named afterWilliam Shakespeare (1564–1616), the English renaissance dramatist and poet.[2] The approved naming citation was published by theMinor Planet Center on 29 September 1985 (M.P.C. 10044).[10]
Three different rotationallightcurves, obtained fromphotometric observations taken at thePalomar Transient Factory and a group of seven observatories, respectively, found a concurringrotation period of 6.06–6.08 hours with a brightness variation between 0.37 and 0.53magnitude (U=2/3/2).[6][7][8]
According to the space-basedNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, the body has analbedo of 0.26 and measures 10.5 kilometers in diameter,[4][5] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Koronis family of 0.24 and calculates a diameter of 10.3 kilometers with anabsolute magnitude of 12.1.[3]
