Near-Earth object / ID: 2177614
177614 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 814m - 1.8km across. It has been followed since 2001-03-12 across 954 recorded observations. Its next approach to Earth is 2035-Sep-18 08:27, passing at 42.164 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.
