Near-Earth object / ID: 2170903
170903 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 609m - 1.4km across. It has been followed since 2002-10-28 across 1566 recorded observations. Its next approach to Earth is 2028-Mar-13 21:39, passing at 34.447 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.
