Near-Earth object / ID: 2175729
175729 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 217m - 485m across. It has been followed since 1998-01-25 across 244 recorded observations. Its next approach to Earth is 2031-Jan-02 12:04, passing at 64.148 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.
