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.

6966 Vietoris           Discovered 1991 Sept. 13 by L. D. Schmadel and F. Börngen at Tautenburg.
Named in honor of Leopold Vietoris (b. 1891), professor emeritus of mathematics of the Leopold-Franzens-University in Innsbruck, on the occasion of his forthcoming 107th birthday. Vietoris is the oldest full member of the Austrian Academy of Sciences and a highly decorated scientist. He made fundamental contributions to algebraic and set-theory topology, and he also wrote outstanding papers on the theory of real functions and on applied mathematics. Named by the first discoverer following a suggestion by H. Haupt, who prepared the citation.
