Near-Earth object / ID: 2002135
2135 Aristaeus 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 652m - 1.5km across. It has been followed since 1977-04-17 across 61 recorded observations. Its next approach to Earth is 2039-Jul-27 13:45, passing at 19.049 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.
