Near-Earth object / ID: 2014827
14827 Hypnos 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 460m - 1km across. It has been followed since 1986-05-04 across 378 recorded observations. Its next approach to Earth is 2048-Dec-13 19:09, passing at 14.705 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.
