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.

12896 Geoffroy           Discovered 1998 Aug. 26 by E. W. Elst at the European Southern Observatory.
Etienne Geoffroy Saint-Hilaire (1772-1844) established in Philosophie anat-omique (2 volumes, 1818-1822) the principle of unity of organic composition among vertebrates (and later also invertebrates). Opposing Cuvier, Geoffroy's concepts created a receptive scientific audience for Darwin's evolution theory.
