Near-Earth object / ID: 2164207
164207 Cardea 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 154m - 344m across. It has been followed since 2001-05-11 across 367 recorded observations. Its next approach to Earth is 2027-Oct-14 19:19, passing at 73.740 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.
