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.

| Mikhail Alexandrovich Smirnov (1954-2006), on the staff of the Institute of Astronomy of the Russian Academy of Sciences, studied the minor bodies of the solar system, artificial satellites and the evolution of galaxies. He also made a contribution to popular astronomy in Russia. The name was suggested by S. I. Barabanov. |
