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.

| 14032 Mego | Discovered 1994 Dec. 4 by M. Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory. |
| Princess Mego (1568-1653) was the wife of Datemasamune, a feudal lord in the Sendai area. After marriage she took the name Yotuko-in. Her birthplace in Miharu, Fukushima prefecture, is famous for a very old cherry tree, Takisakura. A seedling planted near the Sendai Observatory is known as the "Princess Mego Cherry Tree". |
