Near-Earth object / ID: 2012538
12538 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 1.7km - 3.8km across. It has been followed since 1987-08-22 across 11576 recorded observations. Its next approach to Earth is 2042-May-03 07:22, passing at 11.362 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.
