5026 Martes (prov. designation: 1987 QL1) is a carbonaceous asteroid from the inner region of the asteroid belt, approximately 9 kilometers (6 miles) in diameter. It was discovered on 22 August 1987, by Czech astronomer Antonín Mrkos at Kleť Observatory in the Czech Republic.[10] It is named after the two weasel-like animal species: pine marten and beech marten.[2]
Martes is the namesake member of a small asteroid family, named the Martes family.[citation needed] It orbits the Sun in the inner main-belt at a distance of 1.8–3.0 AU once every 3 years and 8 months (1,339 days). Its orbit has an eccentricity of 0.24 and an inclination of 4° with respect to the ecliptic.[1]
A first precovery was taken at Palomar Observatory in 1953, extending the body's observation arc by 34 years prior to its official discovery observation at Klet.[10]
Naming
This minor planet was named for the two species of the family Mustelidae, the pine marten and beech marten. They also live in the forests near the discovering Kleť Observatory.[2] The official naming citation was published by the Minor Planet Center on 22 June 1999 (M.P.C. 34920).[11]
