Near-Earth object / ID: 2003361
3361 Orpheus is a near-Earth object of the APO orbit class — Near-Earth asteroid orbits which cross the Earth’s orbit similar to that of 1862 Apollo. Radar and photometric estimates put it between 335m - 748m across. It has been followed since 1982-04-24 across 3216 recorded observations. Its next approach to Earth is 2029-Nov-14 21:40, passing at 32.756 LD. JPL classifies it as a potentially hazardous asteroid, a label driven by its size and how close its orbit comes to ours — not by a predicted impact.
