The Nine Planets is a collection of information about our Solar System intended for a general audience with little technical background. No special expertise or knowledge is needed; all technical and astronomical terms and proper names are defined in the glossary. The bulk of this material should be familiar to planetary scientists and astronomers but they may find a few interesting tidbits, too.
This document consists of about 60 WWW "pages", one page for each major body in the Solar System. Each page has:
To truly justify the title of "Multimedia Tour", I've also included:
There are also a few miscellaneous pages: on planetary science spacecraft, the glossary, a comprehensive list of planetary images available elsewhere on the Net, some bits of history, several pages of data and a special plea for your support of the space program.
The pages of this document are organized in a hierarchy based on the primary-satellite relationship. In addition, there are many hyperlinks enabling the interactive viewer to jump around and view the pages in many ways. (If you "get lost" you can always jump back to the table of contents.)
At the bottom of each page is a set of links to other related pages. To visit the next body in an ordered traversal of the solar system choose the link immediately to the right of the name of the current page. You can also go back to the previous page, the "parent" page, the table of contents or to the detailed data page.
I've chosen ten of the most interesting bodies and linked them into an Express Tour. If you don't have time for the full tour, don't miss these.
If you're having trouble viewing something, see the Technical Help appendix for some hints.
It will also go faster (for you and everyone else) if you use the mirror site closest to you.
