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.

4193 Salanave           Discovered 1981 Sept. 26 by B. A. Skiff and N. G. Thomas at the Anderson Mesa Station of the Lowell Observatory.
Originally a meteorologist, as first executive officer of the Astronomical Society of the Pacific and first editor of Mercury, Leon E. Salanave took steps to ensure that amateur astronomers felt a sense of "belonging" to an organization dominated by professionals. The name was suggested by W. J. Westbrooke.
