Near-Earth object / ID: 2177049
177049 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 291m - 652m across. It has been followed since 2002-05-17 across 348 recorded observations. Its next approach to Earth is 2029-Oct-04 02:09, passing at 15.711 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.
