Near-Earth object / ID: 2144332
144332 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 1.3km - 2.8km across. It has been followed since 1955-04-24 across 2148 recorded observations. Its next approach to Earth is 2035-Sep-10 20:18, passing at 36.429 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.
