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.

| 11727 Sweet | Discovered 1998 May 1 by the Near-Earth Asteroid Tracking Team (NEAT) at Haleakala. |
| During the 1.2-m Schmidt conversion Merle Sweet (b. 1942), assistant superintendent at the Palomar Observatory, assisted in overseeing the details in the layout and construction of the slip-ring trolleys. He also worked in the rewiring of the dome. The name was suggested by R. Thicksten. |
