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.

| 58424 Jamesdunlop | Discovered 1996 Feb. 22 by M. Tichy and Z. Moravec at Klet. |
| James Dunlop (1793-1848) was an early figure of Australian astronomy. He made several noteworthy discoveries and wrote A Catalogue of Nebulae and Clusters of Stars in the Southern Hemisphere observed in New South Wales. He is also credited with the discovery of comet C/1833 S1 (Dunlop). |
