Near-Earth object / ID: 2154590
154590 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 121m - 272m across. It has been followed since 1998-01-29 across 123 recorded observations. Its next approach to Earth is 2029-Apr-05 01:10, passing at 26.285 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.
