Near-Earth object / ID: 2162421
162421 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 635m - 1.4km across. It has been followed since 1977-02-18 across 743 recorded observations. Its next approach to Earth is 2035-Feb-19 20:56, passing at 51.759 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.
