Near-Earth object / ID: 2140288
140288 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 1.2km - 2.7km across. It has been followed since 1996-08-14 across 535 recorded observations. Its next approach to Earth is 2027-Mar-12 09:05, passing at 49.427 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.
