5385 Kamenka, provisional designation Шаблон:Mp, is a background asteroid from the outer regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 3 October 1975, by Soviet astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula.[1] The presumed C-type asteroid has a rotation period of 6.68 hours.[2] It was named for the Ukrainian town of Kamianka.[1]

Orbit and classification

Kamenka is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the outer asteroid belt at a distance of 2.4–3.9 AU once every 5 years and 7 months (2,049 days; semi-major axis of 3.16 AU). Its orbit has an eccentricity of 0.23 and an inclination of 10° with respect to the ecliptic.[4] The body's observation arc begins with a precovery taken at Palomar Observatory in March 1955, twenty years prior to its official discovery observation at Nauchnij.[1]

Physical characteristics

Kamenka is an assumed carbonaceous C-type asteroid.[2]

Rotation period

Two rotational lightcurves of Kamenka have been obtained from photometric observations at the Palomar Transient Factory and at the Oakley Southern Sky and Oakley Observatory.[5][6] Lightcurve analysis gave a rotation period of 5.93 and 6.683 hours with a brightness amplitude of 0.26 and 0.15 magnitude, respectively (Шаблон:Small).[2]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Kamenka measures between 14.10 and 16.768 kilometers in diameter and its surface has an albedo between 0.083 and 0.11.[7][8][9][10]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 20.21 kilometers based on an absolute magnitude of 12.2.[2]

Naming

This minor planet was named after the town of Kamianka (Шаблон:Lang-uk; Шаблон:Lang-ru), located in the Cherkasy Oblast region of central Ukraine.[1] The official naming citation was published by the Minor Planet Center on 24 January 2000 (Шаблон:Small).[11]
