Near-Earth object / ID: 2011500
11500 Tomaiyowit 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 560m - 1.3km across. It has been followed since 1989-10-25 across 1521 recorded observations. Its next approach to Earth is 2028-May-10 08:50, passing at 38.978 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.
