I've had fair luck simply using a sphere with a turbulated bozo pattern and an
appropriate color_map.  Also, layered textures work pretty well.

You might want to check out Matthew Corey Brown's "How to Make a Moon" tutorial
(http://www.xenoarch.com/tutorials/moon.html)  The page mainly is intended as an
isosurface tutorial, but the non-iso that heads it up is pretty good, too.

Good luck!
