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.

10358 Kirchhoff           Discovered 1993 Oct. 9 by E. W. Elst at the European Southern Observatory.
Gustav Robert Kirchhoff (1824-1887) was a German physicist who, together with Robert Bunsen, founded the discipline of spectrum analysis. They demonstrated that an element gives off a characteristic colored light when heated to incandescence.
