The Fredösphere

I'd like to  recommend to you a wonderful tool for surfing the solar system.  It's called Celestia and it 's an OpenGL-based application you can download for free.  It seems to be a project started by a guy with a surplus of brains and spare time.

Once you have it running, you can fly from planet to planet, or sit tight and watch, say, Ganymede slowly work its way past Jupiter.  Go to the options dialog and make the orbits visible; see Pluto's eccentric path and you will be forever cured of the ridiculous notion that it deserves to be called a planet.

Der Drubermensch mastered this thing before his fifth birthday and by playing with it he learned the names of the planets and their moons.  Did I mention it is wonderful?
