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.

1815 Beethoven (1932 CE1)          Discovered 1932-Jan-27 by Reinmuth, K. at Heidelberg
Discovery is clearly Jan. 27, although this object was originally thought to be planet 820. By error a provisional designation 1932 CE1 instead of a B designation was assigned.
Note: "planet" implies "minor planet"
