Near-Earth object / ID: 2136849
136849 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 767m - 1.7km across. It has been followed since 1998-02-09 across 760 recorded observations. Its next approach to Earth is 2027-Jul-19 00:03, passing at 29.783 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.
