Dione (moon)
Dione is the fourth largest moon of Saturn.[1] It has a diameter of 1,123 km (698 miles).[2] It was discovered in 1684 by Giovanni Domenico Cassini.[2] It is named after the titan Dione in Greek mythology. The moon has many craters and ice cliffs.[2] It is tidally locked with Saturn, meaning the same face of Dione always faces Saturn.[2]
