Near-Earth object / ID: 2144900
144900 is a near-Earth object of the ATE orbit class — Near-Earth asteroid orbits similar to that of 2062 Aten. Radar and photometric estimates put it between 590m - 1.3km across. It has been followed since 2004-11-13 across 535 recorded observations. Its next approach to Earth is 2039-Dec-10 09:08, passing at 23.949 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.
