Nine Planets.org is a large collection information and images designed to be used as a virtual tour of the solar system. The information on Nine Planets.org is organized by planet working progressively away from the sun. Nine Planets.org also provides information and images on smaller bodies in the solar system.

Applications for Education
Nine Planets advertises itself as a virtual tour, it’s not the type of tour that will instantly engage students. Nine Planets is best used as a reference resource as the content itself is excellent although the layout is not great. Teachers should find the lesson plan links quite useful.

If you’re looking for more space science resources take a look at Celestia, SkyServer, and Microsoft’s World Wide Telescope.
