Near-Earth object / ID: 2138175
138175 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 212m - 474m across. It has been followed since 2000-03-11 across 1621 recorded observations. Its next approach to Earth is 2026-Nov-08 08:22, passing at 35.553 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.
