Near-Earth object / ID: 2153311
153311 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 880m - 2km across. It has been followed since 1989-07-01 across 254 recorded observations. Its next approach to Earth is 2068-Aug-12 07:28, passing at 27.554 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.
