Near-Earth object / ID: 2001981
1981 Midas 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 2.3km - 5.2km across. It has been followed since 1973-03-06 across 2498 recorded observations. Its next approach to Earth is 2032-Sep-14 14:57, passing at 33.590 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.
