2807 Karl Marx, provisional designation1969 TH6, is a carbonaceous Dorianasteroid from the central region of theasteroid belt, approximately 17 kilometers in diameter. It was discovered on 15 October 1969, by Russian astronomerLyudmila Chernykh at theCrimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[3] The asteroid was later named for the German philosopherKarl Marx.[2]
Karl Marx is a member of theDora family (512), a well-determinedasteroid family of more than 1,200 known members with a carbonaceous composition. The family's namesake is668 Dora. It is alternatively known as the "Zhongolovich family", named after its presumably largest member1734 Zhongolovich. The Dora family may also contain a subfamily.[4][6]: 13, 23
It orbits the Sun in thecentral main-belt at a distance of 2.3–3.3 AU once every 4 years and 8 months (1,707 days). Its orbit has aneccentricity of 0.18 and aninclination of 8° with respect to theecliptic.[1]
The asteroid was first identified as1924 BE atHeidelberg Observatory in 1924. Its first used observation is aprecovery taken atPalomar Observatory in 1954, extending the body'sobservation arc by 15 years prior to its official discovery observation at Nauchnyj.[3]
In theSMASS classification,Karl Marx is classified as a carbonaceousC-type asteroid.[1] According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Karl Marx measures 16.9 kilometers in diameter and its surface has analbedo of 0.057.[5]
As of 2017, no rotationallightcurve ofKarl Marx has been obtained. The body'srotation period and shape remains unknown.[1][7]
Thisminor planet was named after German philosopher, economist and revolutionary socialistKarl Marx (1818–1883), student of the theories about society, economics and politics, and author ofDas Kapital, the foundational theoretical text of moderncommunist thought.[2] The official naming citation was published by theMinor Planet Center on 24 July 1983 (M.P.C. 8065).[8]
