I recently showed some samples of high detail rendering of the earth with
variable level of detail.  See:

Subject: rendering the earth (71k+68k)
Date: Tue, 01 Apr 2003 22:57:55 +0200
From: Christoph Hormann <chr### [at] gmxde>
Newsgroups: povray.binaries.images

The data the renders are based on would result in ~3.5 billion triangles
when rendered as a whole with a mesh.  

You can apply the same method (i.e. rendering a planetary body with an
isosurface defined by image maps, using higher resolution data for the
foreground part and blending with the lower resolution basis using
functions) to any other planet.
