Near-Earth object / ID: 2138727
138727 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 360m - 805m across. It has been followed since 2000-09-27 across 180 recorded observations. Its next approach to Earth is 2052-Oct-19 18:24, passing at 149.271 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.
