Near-Earth object / ID: 2031669
31669 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 1.5km - 3.4km across. It has been followed since 1996-06-12 across 1849 recorded observations. Its next approach to Earth is 2027-Feb-18 09:31, passing at 60.967 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.
