Rhea (/ˈr.ə/) is the second-largest moon of Saturn and the ninth-largest moon in the Sol System, with a surface area that is comparable to the area of Australia. It is the smallest body in the Sol System for which precise measurements have confirmed a shape consistent with hydro-static equilibrium.[11] It was discovered in 1672 by Giovanni Domenico Cassini.
