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.

7767 Tomatic           Discovered 1991 Sept. 13 by L. D. Schmadel and F. Börngen at Tautenburg.
Named in honor of A. U. Tomatic (b. 1997), collaborator at the Minor Planet Center. An ardent computer of orbits and distributor of observational data of minor planets and comets, Tomatic published his first contribution to this field on MPEC 1997-Y01 (1997 Dec. 16). Tomatic is a godchild of the MPC astronomers B. G. Marsden and G. V. Williams. Name proposed by the first discoverer in gratitude for Tomatic's indefatigable service.
