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.

11881 Mirstation           Discovered 1990 Aug. 20 by E. W. Elst at the European Southern Observatory.
The Russian space station Mir, launched in 1986, remained in service for more than 15 years as a laboratory for a wealth of scientific experiments performed on board by international crews. Mir was destroyed in March 2001 in order to avoid an uncontrolled return into the earth's atmosphere.
