(7767) Tomatic Main-belt Asteroid
Discovered on 13 September 1991 by Schmadel, L. D., Borngen, F. 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.Naming citation (19990402/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
