2985 Shakespeare, provisional designation 1983 TV1, is a stony Koronian asteroid from the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 12 October 1983, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona.[10]

The S-type asteroid is a member of the Koronis family, a group consisting of about 200 known bodies. It orbits the Sun at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,756 days). Its orbit has an eccentricity of 0.05 and an inclination of 3° with respect to the ecliptic.[1]

Three different rotational light-curves, obtained from photometric observations taken at the Palomar Transient Factory and a group of seven observatories, respectively, found a concurring rotation period of 6.06–6.08 hours with a brightness variation between 0.37 and 0.53 magnitude (U=2/3/2).[6][7][8] According to the space-based NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the body has an albedo of 0.26 and measures 10.5 kilometers in diameter,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Koronis family of 0.24 and calculates a diameter of 10.3 kilometers, based on an absolute magnitude of 12.1.[3]

The minor planet was named after William Shakespeare (1564–1616), the English renaissance dramatist and poet.[2] Naming citation was published on 29 September 1985 (M.P.C. 10044).[11]
