Near-Earth object / ID: 2168318
168318 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 415m - 929m across. It has been followed since 1989-02-27 across 1060 recorded observations. Its next approach to Earth is 2043-Mar-15 05:24, passing at 73.115 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.
