2892 Filipenko, provisional designation 1983 AX2, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 60 kilometers in diameter.

The asteroid was discovered on 13 January 1983, by Russian female astronomer Lyudmila Karachkina at Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[9] It was named after surgeon Aleksandr Filipenko.[2]

Orbit and classification

Filipenko is a dark asteroid that orbits the Sun in the outer main-belt at a distance of 2.5–3.8 AU once every 5 years and 8 months (2,066 days). Its orbit has an eccentricity of 0.21 and an inclination of 17° with respect to the ecliptic.[1]

First identified as A910 CK at Taunton Observatory (

Turku Observatory in 1953, extending the body's observation arc by 30 years prior to its official discovery observation at Nauchnyj.[9]
