For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

7958 Leakey           Discovered 1994 June 5 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Named for Mary Leakey (1913-1996), her husband Louis Leakey (1903-1972) and her son Richard Leakey (b. 1944), all major figures in the paleoanthropology of Africa. Mary and Louis worked together for 30 years and proved that human evolution was centered in Africa, rather than in Asia. Many of their most important discoveries were made at Olduvai Gorge in Tanzania. With his team in Kenya, Richard Leakey discovered that the Koobi Fora site contained one of the richest and most varied assemblages of early human remains anywhere in the world.
