Titan May Have an Ocean

olsmeister writes "Titan has been a particular focus of attention because of its dense, complex atmosphere, its weather and its lakes and oceans. Now it looks as if Titan is even stranger still. The evidence comes from careful observations of Titan's orbit and rotation. This indicates that Titan has an orbit similar to our Moon's; it always presents the same face toward Saturn and its axis of rotation tilts by about 0.3 degrees. This data allows astronomers to work out Titan's moment of inertia and points to something interesting. The numbers indicate that Titan's moment of inertia can only be explained if it is a solid body that is denser near the surface than it is at its center."

Incomplete summary!

[ThunderBird89]

If there's one thing that should be included there, it's that the 'ocean' isn't a surface ocean, like Earth's, but a SUBSURFACE one, like Europa's!

Editors, for fuck's sake, please check the submissions, not only for grammar, but for factual accuracy too!

He didn't claim it was a surface ocean either. You're just adding an adjective, not proving him wrong.

Re:Grammar Check

It's less of a summary and more of a copy/paste straight from the article. The weird comma after the first word comes from the fact that they didn't copy/paste the whole sentence, probably mistaking the word Titan for the start of the sentence because it has a capital letter and just happened to break into a new-line of the article. The full sentence is:

Saturn's largest moon, Titan, has been a particular focus of attention because of its dense, complex atmosphere, its weather and its lakes and oceans.

Re:ice float because it's LESS dense!

Um, water ice floats because of a peculiarity in H20. Most solids are actually denser than their liquid forms.
