Saturn's large moon Titan
would be unique in our solar system, the
only world with
lakes and seas on its surface ... except for
planet Earth of course.
Centered on the north pole,
colorized map shows Titan's
bodies of methane and ethane in blue and black, still
at frigid surface temperatures of -180 degrees C (-292 degrees F).
The map is based on data from the Cassini spacecraft's radar, taken during
2004 and 2013.
Roughly heart-shaped, the lake above and right of the pole is
Ligeia Mare, the second largest known body of liquid on Titan and larger
Superior on Earth.
Just below the north pole is Punga Mare.
The sprawling sea below and right of Punga is the
Kraken Mare, Titan's largest
Above and left of the pole,
the moon's surface is dotted with smaller lakes
that range up to 50 kilometers across.
