Near-Earth object / ID: 2155338
155338 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 221m - 494m across. It has been followed since 2002-06-16 across 134 recorded observations. Its next approach to Earth is 2053-Nov-10 21:40, passing at 50.443 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.
