Near-Earth object / ID: 2137126
137126 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 644m - 1.4km across. It has been followed since 1999-01-15 across 1228 recorded observations. Its next approach to Earth is 2046-Aug-23 11:38, passing at 21.998 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.
