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.

5953 Shelton           Discovered 1987 Apr. 25 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Named in honor of Ian Shelton, Canadian astronomer, best known for his discovery of the supernova in the Large Magellanic Cloud on 1987 Feb. 24. During his four years as resident observer at the University of Toronto Southern Observatory, he participated in programs with astronomers worldwide, and more recently he has generously contributed to the astronomical education of school children, parents and teachers. Name suggested and citation prepared by D. MacCormack and R. Garrison.
