Near-Earth object / ID: 2143649
143649 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 884m - 2km across. It has been followed since 2003-08-24 across 1250 recorded observations. Its next approach to Earth is 2031-Mar-19 05:27, passing at 33.663 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.
