This is activity C10 from The Universe at Your Fingertips 2.0, a DVD-ROM resource collection for teaching astronomy.
The most direct and dramatic proof of the heliocentric model of the solar system came from Galileo’s observations of the phases (different appearances of sunlit and dark areas) on the disk of the planet Venus as seen through his telescope. Here students learn about phases and then compare the motion of Venus around the Sun in two models and how it would produce phases as seen from Earth.
