Near-Earth object / ID: 2144898
144898 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 443m - 991m across. It has been followed since 2002-02-16 across 1450 recorded observations. Its next approach to Earth is 2032-May-01 22:37, passing at 8.165 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.
