Near-Earth object / ID: 2164211
164211 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 335m - 748m across. It has been followed since 2004-05-15 across 482 recorded observations. Its next approach to Earth is 2032-Jul-11 01:59, passing at 37.827 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.
