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.

| 199950 Sierpc | Discovered 2007 Apr. 16 at the Astronomical Research Institute in Charleston. |
| Sierpc is one of the oldest towns in the Mazovie Region of Poland, established at the turn of the 11th century. It is situated at the crossroads of Prussia and Cracow, and is a pivotal railway junction in Poland. Since 2007, high schools in Sierpc have been active in minor-planet discoveries as part of IASC. |
