Near-Earth object / ID: 2139359
139359 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 1.3km - 3km across. It has been followed since 2001-05-25 across 740 recorded observations. Its next approach to Earth is 2029-Jun-10 04:49, passing at 244.203 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.
