Near-Earth object / ID: 2143992
143992 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 1.6km - 3.5km across. It has been followed since 1985-01-21 across 1242 recorded observations. Its next approach to Earth is 2028-Aug-20 14:12, passing at 65.457 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.
