Solar System Scope is an online 3-D interactive simulation of, yes, the solar system. The controls are simple and intuitive, but since everything is well labeled, you can just follow the on-screen directions. Click to begin . . . drag background to move camera view . . . double click to visit a planet . . . use menu to select a new view. Mood music plays in the background, but you can mute if it becomes too much. This is a new website, and not all of the controls are functional yet, so watch for updates. Take a look even if you're not teaching planets or the solar system right now.
