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.

6449 Kudara           Discovered 1991 Feb. 7 by T. Seki at Geisei.
Named in memory of Kyoyu Kudara (1894-1964), Japanese astronomer and Buddhist priest. A staff member of the Tokyo Astronomical Observatory from 1917 to 1925, he recovered comet 10P/Tempel 2 in 1920 according to his own prediction, and he observed this comet again in 1925. Later he taught positional astronomy and the science of the calendar at Kyoto University. One of the cofounders of the Oriental Astronomical Association, he served as its president from 1959 to 1964. Name proposed by the discoverer following a suggestion by I. Hasegawa and T. Sato. Citation by I. Hasegawa.
