The Nine Planets
A Multimedia Tour of the Solar System: describes the history, mythology and current scientific knowledge of each of the planets and moons and other objects in our solar system. In addition to the usual pictures, there are also sounds, an occasional movie and many links to other net resources. The text is written for a general audience not necessarily knowledgeable in astronomy; technical terms are linked to an extensive glossary.
