525 Adelaide (A908 UJ)          Discovered 1908-Oct-21 by Metcalf, J. H. at Taunton
The original planet 525 Adelaide, discovered 1904 Mar. 14 by M. Wolf, Heidelberg, was observed only during the discovery opposition. In 1958 A. Patry, Nice, found that this object is identical with planet 1171 Rusthawelia, discovered 1930 Oct. 3 by S. Arend, Uccle. This planet retains the latter designation 1171 Rusthawelia. The older designation 525 Adelaide has been given to a minor planet discovered 1908 Oct. 21 by J. H. Metcalf and newly catalogued.
Note: "planet" implies "minor planet"
