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.

| 5833 Peterson | Discovered 1991 Aug. 5 by H. E. Holt at Palomar. |
| Colin A. Peterson (b. 1977), a research support specialist at Cornell University, and responsible for designing sequences for the NEAR spacecraft Multi-Spectral Imager and Near-Infrared Spectrometer team, has developed innovative methods for obtaining spectral maps of (433) Eros. The name was suggested by J. Veverka. |
