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.

100000 Astronautica           Discovered 1982 Sept. 28 by J. Gibson at Palomar.
This minor planet is being named Astronautica to recognize the fiftieth anniversary of the start of the Space Age, inaugurated by the launching of the first artificial earth satellite on 1957 Oct. 4. The name is associated with this significant number, as space is defined to begin at an altitude of 100~000 meters above the earth's surface.
