An aquatic planet?

[Silversmok3]

After reading the last Titan novel,it begs the question-is it possible to have a planet made entirely of water?Meaning no landmass visible?

 

[All Seeing Eye]

Yes.

It is theroized that there could be super-earths with a metal core, silicate mantle and solid/liquid water outer layers.
Here is one paper:http://arxiv.org/PS_cache/astro-ph/pdf/0610/0610122v1.pdf

I imagine it's possible... but the tides on such a planet would be something to behold, with no physical obstruction to the movement of water.

First thought that comes to mind would be a water mass constantly rotating around the center of the planet. Not an expert though.

Atmosphere is a fluid. Your thought that a water world is something unusual would be out.

Water collects in Zero G with Other Water building a continuously growing Mass as more and more water falls into orbit of the Large water centre...Even Something Like Earth might Become a Waterworld over time as Solar Hydrogen collides with Oxygen in the upper atmosphere and becomes water. A few billion years down the line we could have a complete replacement of our "Gaseous" Atmosphere with Water.

The water would also be heated from the sun and from below, so those details plus the local composition would go into the global and local flows. Of course the planetary rotation rate is important.

There essentially is an ocean planet in our own solar system. It's a moon orbiting another planet, and it's ocean is frozen over; but Europa essentially fits the bill.
