Near-Earth object / ID: 2085640
85640 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 157m - 352m across. It has been followed since 1998-07-26 across 277 recorded observations. Its next approach to Earth is 2056-Mar-21 02:44, passing at 34.911 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.
