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. \

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
