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.

8700 Gevaert           Discovered 1993 May 14 by E. W. Elst at the European Southern Observatory.
Lieven Gevaert (1868-1935) was a Belgian industrialist who established the "N.V. Gevaert Photo-Producten" at Mortsel, near Antwerp, beginning in 1890 with a small shop of homemade photographical paper. Gevaert glass plates have been used for many purposes in astronomy, especially for the astrometry of minor planets.
