Titan is a fun puzzle.
It has a synchronous rotation, same face faces Saturn as our moon, yet of course, seems very active for a moon.
Some links I've found, topics I've been curious about regarding Titan:

*Sorry, Raoul..no html...being summoned. I still say there's volcanic activity on Titan and I'm now agreeing that it may have been hit by some of the same comets/cometary fragment as Earth. Cheers!
