The bright spot labeled "Xanadu" near longitude 90 degrees on this body's surface serves as a contrast to the dark lines around its equator. The atmosphere contains predominantly nitrogen and hydrocarbons, giving this moon an orange hue. Although methane is below its saturation pressure, this moon's lakes and rivers are probably made of ethane rather than methane. Discover
