Near-Earth object / ID: 2197588
197588 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 1km - 2.2km across. It has been followed since 2000-09-21 across 207 recorded observations. Its next approach to Earth is 2142-Feb-20 23:28, passing at 61.823 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.
