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.

| 12173 Lansbergen | Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. |
| Philippus Lansbergen (1561-1632), Calvanist minister and active astronomical researcher in Middelburg, The Netherlands, in 1629 wrote the first popular book on astronomy in the Dutch language. The book promoted the Copernican system and became a best seller. |
