    3174 Alcock, provisional designation 1984 UV, is a carbonaceous Themistian asteroid from the outer region of the asteroid belt, approximately 19 kilometers in diameter. It was discovered by American astronomer Edward Bowell at Lowell's U.S. Anderson Mesa Station in Flagstaff, Arizona, on 26 October 1984.[7]

    The dark C-type asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,037 days). Its orbit has an eccentricity of 0.17 and an inclination by 2° to the plane of the ecliptic. The first used precovery was taken at Crimea–Nauchnij in 1973, extending the asteroid's observation arc by 11 years prior to its discovery. However, the first images were already taken at the U.S. Goethe Link Observatory in 1962.[7]

    A rotational light-curve of this asteroid was obtained from photometric observations made by French astronomer René Roy in February 2008. The light-curve gave a rotation period of 7.05±0.01 hours with a brightness variation of 0.65 in magnitude (U=3-).[5] According to the spaced-based survey carried out by the Japanese Akari satellite, the asteroid measures 18.66 kilometers in diameter and its surface has an albedo of 0.102,[4] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.08 and calculates a diameter of 18.71 kilometers.[3]

    The minor planet was named by the discoverer for prolific British amateur astronomer George Alcock (1912–2000), who visually discovered 5 comets and 4 novae.[2] Naming citation was published on 5 November 1987 (M.P.C. 12458).[8]
