Near-Earth object / ID: 2163243
163243 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 1.4km - 3.1km across. It has been followed since 2002-03-18 across 1995 recorded observations. Its next approach to Earth is 2027-Feb-22 02:11, passing at 38.826 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.
