Near-Earth object / ID: 2004953
4953 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 2.8km - 6.3km across. It has been followed since 1974-07-21 across 3479 recorded observations. Its next approach to Earth is 2027-Jun-06 22:43, passing at 11.993 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.
