2985 Shakespeare, provisional designation 1983 TV1, is a stony asteroid from the outer region of the asteroid belt, about 10 kilometers in diameter. It was discovered by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona, on 12 October 1983.[8]

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 (1,755 days). Its orbit shows an eccentricity of 0.05 and is tilted by 3 degrees to the plane of the ecliptic. Three different photometric light-curve observations found a concurring rotation period of 6.1 hours.[5][6][7] According to the space-based NEOWISE mission of the Wide-field Infrared Survey Explorer, the body has an albedo of 0.26, while the Collaborative Asteroid Lightcurve Link assumes a slightly lower value of 0.24.[3][4]

The minor planet was named after William Shakespeare (1564–1616), the English renaissance dramatist and poet.[2]
