This site, 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. Data for each planet includes orbit, diameter, mass, motions, composition, albedo, number of satellites, and visits by probes from Earth. Links to solar system data, a discovery chronology, planetary linguistics, and astronomical names are also provided. The site is available in several languages, including French and Spanish, by accessing the mirror sites.
