    2127 Tanya, provisional designation 1971 KB1, is a dark asteroid in the outer region of the asteroid belt, about 39 kilometers in diameter. It was discovered by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 29 May 1971.[5] The assumed carbonaceous C-type asteroid has a low geometric albedo of 0.06. It orbits the Sun at a distance of 3.1–3.3 AU once every 5 years and 9 months (2,105 days).[1]

    Light curve measurements from the Palomar Transient Factory Survey, gave a rotation period of 7.8640±0.0211 hours with an amplitude of 0.18 in magnitude.[3]

    Lyudmila Chernykh named her discovery in memory of the young Russian girl Tanya Savicheva, who died after the Siege of Leningrad (1941–1944) and wrote a well-known diary.[2]
