Near-Earth object / ID: 2136617
136617 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 677m - 1.5km across. It has been followed since 1988-09-14 across 743 recorded observations. Its next approach to Earth is 2032-Sep-01 09:37, passing at 43.055 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.
