Near-Earth object / ID: 2004183
4183 Cuno 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 3.9km - 8.7km across. It has been followed since 1959-06-05 across 5446 recorded observations. Its next approach to Earth is 2051-Jun-09 12:47, passing at 75.983 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.
