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.

| 31028 Cerulli | Discovered 1996 Apr. 18 at the Osservatorio San Vittore. |
| Italian astronomer Vincenzo Cerulli (1859-1927) founded the private Collurania Observatory near Teramo, where he discovered the bright minor planet (704) Interamnia in 1910 and observed Mars and several comets. He arranged for the observatory to be donated to his country on his death. |
