Near-Earth object / ID: 2163899
163899 is a near-Earth object of the ATE orbit class — Near-Earth asteroid orbits similar to that of 2062 Aten. Radar and photometric estimates put it between 818m - 1.8km across. It has been followed since 2000-01-06 across 1935 recorded observations. Its next approach to Earth is 2027-Nov-12 18:17, passing at 53.755 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.
