Near-Earth object / ID: 2163051
163051 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 1.4km - 3.2km across. It has been followed since 1978-02-05 across 2189 recorded observations. Its next approach to Earth is 2058-Oct-19 14:13, passing at 676.316 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.
