International School of Central Switzerland on 11 Oct 09"The site allows the teacher or student to control how they are viewing the solar system. Users can touch and drag to move things around and they have a complete set of controls to change scale, speed of orbits (passing of time), or planetary object to follow. For example, if you follow the Sun, the Sun is stationary and it shows the other planets orbiting the Sun. If you follow the Earth, then it shows the other planetary objects with a stationary Earth."
