Near-Earth object / ID: 2163373
163373 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 415m - 929m across. It has been followed since 1995-10-23 across 1171 recorded observations. Its next approach to Earth is 2034-Jun-14 11:37, passing at 27.801 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.
