Near-Earth object / ID: 2163683
163683 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 414m - 925m across. It has been followed since 2002-12-28 across 274 recorded observations. Its next approach to Earth is 2036-May-14 11:08, passing at 35.137 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.
