Near-Earth object / ID: 2172678
172678 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 445m - 995m across. It has been followed since 2003-12-21 across 517 recorded observations. Its next approach to Earth is 2033-Jun-24 00:07, passing at 6.530 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.
