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.

17617 Takimotoikuo           Discovered 1995 Oct. 28 by K. Endate and K. Watanabe at Kitami.
Ikuo Takimoto (b. 1954) became interested in astronomy after seeing a photograph of Comet Ikeya-Seki. He now photographs sunspots and solar prominences, in both white light and H- \alpha , at the private observatory he completed in 1988.
