2892 Filipenko, provisional designation 1983 AX2, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 60 kilometers in diameter. It was discovered on 13 January 1983, by Russian female asteronomer Lyudmila Karachkina at Crimean Astrophysical Observatory on the Crimean peninsula.[9]

The dark C-type asteroid orbits the Sun at a distance of 2.5–3.8 AU once every 5 years and 8 months (2,064 days). Its orbit has an eccentricity of 0.21 and an inclination of 17° with respect to the ecliptic.[1] The body was first identified as "1910 CK" at the U.S Taunton Observatory (803) in 1907, and its first used observation made at the Finnish Turku Observatory dates back to 1953, extending the asteroid's observation arc by 30 years prior to its official discovery.[9]

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 56.1 and 69.5 kilometers in diameter and its surface has an albedo between 0.030 and 0.046.[4][5][6] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0426 and a smaller diameter of 56.0 kilometers, based on an absolute magnitude of 10.3.[3]

In November 2004, a rotational light-curve for this asteroid was obtained from photometric observations by Robert D. Stephens at the Santana Observatory (646), California, and gave a well-defined rotation period of 14.00±0.01 hours with a brightness variation of 0.21±0.03 magnitude (U=3).[7]

It is named in after of the chief surgeon Aleksandr Grigorevich Filipenko at the hospital in Bakhchisaraj, on the Crimean peninsula. He had saved the life of a friend of the discoverer Lyudmila Karachkina.[2] Naming citation was published on 13 July 1984 (M.P.C. 8913).[10]
