65 Cybele (sib'-a-lee) is one of the largest asteroids in the main belt. The Cybelian asteroids are named after it. As a C-type asteroid it is dark in color and carbonaceous in composition.
It was discovered on March 8 1861 by Ernst Tempel and named after Cybele the earth goddess.
First Cybelian stellar occultation was observed on October 17, 1979 in the Soviet Union. A diameter of 230 km was derived, closely matching the diameter of 237 km determined by the IRAS satellite.
During the same occultation, a hint of a possible 11 km wide satellite was detected. [2]
