Near-Earth object / ID: 2199145
199145 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 582m - 1.3km across. It has been followed since 2005-11-30 across 611 recorded observations. Its next approach to Earth is 2029-Aug-03 02:35, passing at 38.137 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.
