Near-Earth object / ID: 2154275
154275 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 250m - 560m across. It has been followed since 2002-09-30 across 489 recorded observations. Its next approach to Earth is 2029-Dec-25 04:41, passing at 46.532 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.
