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. |
