Near-Earth object / ID: 2162173
162173 Ryugu 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 327m - 731m across. It has been followed since 1986-04-14 across 5124 recorded observations. Its next approach to Earth is 2033-Dec-21 05:53, passing at 18.456 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.
