Near-Earth object / ID: 2037638
37638 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 370m - 828m across. It has been followed since 1993-11-06 across 956 recorded observations. Its next approach to Earth is 2030-Nov-27 16:32, passing at 39.207 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.
