3067 Akhmatova, provisional designation 1982 TE2, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 14 October 1982, by Soviet–Russian female astronomers Lyudmila Zhuravleva and Lyudmila Karachkina at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.[7]

The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,229 days). Its orbit has an eccentricity of 0.14 and an inclination of 5° with respect to the ecliptic.[1] The first used precovery was taken at Goethe Link Observatory in 1962, extending the asteroid's observation arc by 20 years prior to its discovery. However, the body was already imaged at Turku Observatory in 1938.[7]

According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 6.3 and 6.5 kilometers in diameter and its surface has an albedo of 0.269 and 0.285, respectively,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – which derives from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 6.8 kilometers, based on an absolute magnitude of 13.0.[3]

Two rotational light-curves of this asteroid were obtained from photometric observations performed by Czech astronomer Petr Pravec in December 2009 and May 2012. They showed a rotation period of 3.68629 and 3.68589 hours with a brightness variation of 0.30 and 0.24 in magnitude, respectively (U=3/3).[a] Observations at the U.S. Palomar Transient Factory in August 2012, gave another light-curve with a period of 3.6863 hours and an amplitude of 0.40 in magnitude (U=2).[6]

The minor planet was named after Russian modernist poet, Anna Akhmatova (1889–1966), awarded an honorary doctorate by Oxford University.[2] Naming citation was published on 31 May 1988 (M.P.C. 13174).[8]
