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.

| 10648 Plancius | Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. |
| Petrus Plancius (Pieter Platevoet, 1552-1622) was a Dutch theologian, astronomer, navigator and appointed cartographer to the new Dutch East India Company. Plancius depicted the 12 new southern constellations on a globe he constructed in 1598. |
