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.

141 Lumen          Discovered 1875-Jan-13 by Henry, Paul at Paris
In their cooperative program it will probably never be known which of the Henry brothers discovered which planet. With strict impartiality, these discoveries were announced as having been made alternatively by Prosper and by Paul.
Note: "planet" implies "minor planet"
