Google Earth has thousands of uses and overlays. Today, I learned about a bunch of overlays and layers that I had never even thought of before. Frank Taylor at the Google Earth Blog has a collection of overlays and files for representing planets and moons in Google Earth. The Google Earth Blog as files for Mars, Saturn, Jupiter, and a collection of moons throughout the solar system.

Applications for Education
The planets and moons overlays for Google Earth could be useful tools for science teachers and students. These overlays would be a great complement to using a space simulator program like Celestia, Sky Server, or Microsoft’s World Wide Telescope.
