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.

| 42981 Jenniskens | Discovered 1999 Oct. 2 at Ondřejov. |
| Peter Jenniskens (b. 1962), meteor astronomer of NASA Ames, organized several successful airborne missions (Leonid multi-instrument aircraft campaigns) to observe the Leonid returns from 1998 to 2002. He has substantially improved our knowledge of the behavior of meteor streams. |
