Orbit and classification
Dora family
Karl Marx is a member of the Dora family, a well-determined asteroid family of more than 1,200 known members with a carbonaceous composition. The family's namesake is 668 Dora. It is alternatively known as the "Zhongolovich family", named after its presumably largest member 1734 Zhongolovich. The Dora family may also contain a subfamily.Orbit and observation arc
It orbits the Sun in the central main-belt at a distance of 2.3–3.3 AU once every 4 years and 8 months. Its orbit has an eccentricity of 0.18 and an inclination of 8° with respect to the ecliptic.The asteroid was first identified as at Heidelberg Observatory in 1924. Its first used observation is a precovery taken at Palomar Observatory in 1954, extending the body's observation arc by 15 years prior to its official discovery observation at Nauchnyj.
