Near-Earth object / ID: 2137427
137427 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 1999-10-06 across 970 recorded observations. Its next approach to Earth is 2065-Mar-03 19:20, passing at 36.690 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.
