	The Nine Planets
	A Multimedia Tour of the Solar System
	by Bill Arnett

The Nine Planets is an overview of the history, mythology, and current scientific knowledge of each of the planets and moons in our solar system. Each page has text and images, some have sounds and movies, most provide references to additional related information.
Interplanetary spacecraft have revolutionized planetary science. Very little of this document would have been possible without the space program.

How to contact the author (for comments, questions and bug reports)

Our knowledge of our solar system is extensive. But it is far from complete. Some of the worlds have never even been photographed up close. The Nine Planets is an overview of what we know today. We are still exploring. Much more is still to come:

We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time.
-- T. S. Eliot
