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.

8818 Hermannbondi | Discovered 1985 Sept. 5 by H. Debehogne at the European Southern Observatory. |
British cosmologist Hermann Bondi (1919-2005), known for work on the steady-state theory of the universe, had an impressive career that encompassed mathematics, radar technology, energy, defence, ecology and humanism. As director general of the European Space Research Organization he was a leader in space research. |
