141 Lumen (A875 AA)          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"
