As they orbit the Sun, Near-Earth Objects occasionally approach close to Earth. CNEOS calculates the motion of all NEOs forwards to 2200 A.D. and backwards to 1900 A.D., and determines the times and distances of the Earth close approaches. The results are tabulated here. You can customize the contents and organization of the table via the Table Settings pulldown lists.
