For 10 points, name this largest moon of Saturn.
A hand-drawn picture of this body by astronomer Comas Sola displays the limb-darkening effect. Shangri-La is a dark area and Xanadu is a bright region of this body, which makes four orbits for every three orbits that Hyperion makes. This moon, which has the strongest anti-greenhouse effect in the solar system, is home to a body of liquid called Kraken Mare [MAHR-ey], and was once thought to be larger than Ganymede because of its thick atmosphere. Methane likely composes the lakes, rivers, and clouds of this moon, which the Huygens probe landed on in 2005 after separating from the Cassini orbiter.
