Near-Earth object / ID: 2184266
184266 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 336m - 752m across. It has been followed since 2004-11-03 across 584 recorded observations. Its next approach to Earth is 2038-Dec-09 06:02, passing at 87.152 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.
