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.

20106 Morton           Discovered 1995 Aug. 20 by D. D. Balam at the National Research Council of Canada.
Donald C. Morton (b. 1933), was director of the Anglo-Australian Observatory during 1976-1986 and of the Herzberg Institute of Astrophysics in Ottawa during 1986-2000. With a rocket he made the first ultraviolet spectral observations of stars. He played a leading role in the development of the Gemini Observatory.
