Near-Earth object / ID: 2153958
153958 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 568m - 1.3km across. It has been followed since 1983-05-07 across 834 recorded observations. Its next approach to Earth is 2032-Jul-29 03:34, passing at 13.251 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.
