Recent observations of this body have revealed a bright West Virginia- sized spot on its surface just southeast of the Xanadu region. The only noble gas found on it is argon-40, leading to speculation that its primary distinguishing feature is generated by outgassing from the interior. Its surface temperature and atmospheric pressure were first measured by Voyager I, though the most detailed information about this satellite comes from the Huygens probe, which landed on its surface in 2005 and discovered lakes of liquid hydrocarbons near its polar regions. The only satellite in the solar system with clouds and a dense atmosphere, FTP, identify this second largest moon in the solar system and the largest moon of Saturn.
