Near-Earth object / ID: 2141851
141851 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 729m - 1.6km across. It has been followed since 2000-09-20 across 946 recorded observations. Its next approach to Earth is 2031-May-06 15:21, passing at 33.292 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.
