Near-Earth object / ID: 2143487
143487 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 433m - 968m across. It has been followed since 1975-10-06 across 287 recorded observations. Its next approach to Earth is 2034-Mar-23 22:23, passing at 43.245 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.
