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.

1078 Mentha (1926 XB)          Discovered 1926-Dec-07 by Reinmuth, K. at Heidelberg
In 1958 A. Patry, Nice, found that planet 864 Aase, discovered 1917 Feb. 13 by M. Wolf, Heidelberg, is identical with 1078 Mentha, discovered 1926 Dec. 7 by K. Reinmuth, Heidelberg. This object retains the latter designation 1078 Mentha. In 1974 the designation 864 Aase was assigned to planet 1921 KE, discovered 1921 Sept. 30 by K. Reinmuth and newly catalogued.
Note: "planet" implies "minor planet"
