2807 Karl Marx
2807 Karl Marx, provisional designation 1969 TH6, is a carbonaceous asteroid from the outer region of the asteroid belt, roughly 13 kilometers in diameter. It was discovered on 15 October 1969, by Russian female astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. The asteroid is classified as a dark C-type asteroid in the SMASS taxonomy. It orbits the Sun at a distance of 2.3–3.3 AU once every 4 years and 8 months (1,708 days). Its orbit is tilted by 8 degrees to the plane of the ecliptic and shows an eccentricity of 0.18. Little is known about the asteroids exact size, albedo and rotation period, despite having a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc that spans over a period of almost a century, with precovery images on photographic plates already taken in the 1920s. The asteroid is also a member of the Dora family.[citation needed] Based on its absolute magnitude of 12.7, its diameter could be anywhere between 8 and 18 kilometers, assuming an albedo in the range of 0.05 to 0.25. Since the outer main-belt asteroid is of a carbonaceous rather than of a silicaceous composition, with low albedos, typically around 0.05, the asteroid's diameter might be on the upper end of NASA's published conversion table, as the lower the albedo (reflectivity), the larger the body's diameter for a given absolute magnitude (brightness). The minor planet is named after German philosopher, economist and revolutionary socialist Heinrich Karl Marx (1818–1883), student of the theory of socio-economic systems and author of Das Kapital, the foundational theoretical text of modern communist thought.
