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.

7650 Kaname           Discovered 1990 Oct. 16 by T. Seki at Geisei.
Named in memory of Kaname Nakamura (1904-1932), Japanese amateur astronomer and volunteer at the Kwasan Observatory. As a member of W. H. Pickering's League of Mars Observers, he was the first in Japan to make systematic observations of that planet. He was also a pioneer in astronomical optics and made many precision mirrors and lenses. Name proposed by the discoverer following a suggestion by T. Sato and A. Fujii.
