2995 Taratuta, provisional designation 1978 QK, is a stony asteroid from the middle region of the asteroid belt, about 17 kilometers in diameter. It was discovered on 31 August 1978, by Russian astronomer Nikolai Chernykh at Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[8]
The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 3 months (1,546 days). Its orbit is tilted by 15 degrees to the plane of the ecliptic and shows an eccentricity of 0.14.[1] In 2014, a photometric light-curve analysis performed at the U.S. Burleith Observatory in Washington D.C. gave the body a revised rotation period of 11.1 hours,[6] while a previous observation measured a much shorter period of 6.6 hours.[7] The asteroid's geometric albedo of 0.06–0.07 has been determined by the space-satellites IRAS and Akari, with the Collaborative Asteroid Lightcurve Link deriving a somewhat higher value of 0.09.[3][4][5] For a S-type asteroid, this is still an exceptionally low albedo.
The minor planet was named in honor of Evgeniya Aleksandrovna Taratuta, Soviet writer and literary scholar.[2]
