Near-Earth object / ID: 2100085
100085 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 702m - 1.6km across. It has been followed since 1979-06-29 across 663 recorded observations. Its next approach to Earth is 2063-Oct-04 07:06, passing at 520.699 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.
