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.

| 8860 Rohloff | Discovered 1991 Oct. 5 by L. D. Schmadel and F. Börngen at Tautenburg. |
| Ralf-Rainer Rohloff (b. 1960) is a design engineer on the staff of the Max-Planck-Institut für Astronomie, Heidelberg. Head of the construction team, he played an important role in the development of adaptive optics devices for the MPIA and UKIRT telescopes. The name was suggested by the first discoverer. |
