Near-Earth object / ID: 2053550
53550 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 412m - 921m across. It has been followed since 1991-10-04 across 441 recorded observations. Its next approach to Earth is 2044-Sep-08 20:19, passing at 63.153 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.
