English: This is an animation of the 28 images of Saturn shown in Saturnoppositions.jpg (simulated views using a computer program written by Tom Ruen). This animation demonstrates the 29.5-year orbital period of Saturn by opposition date, as well as the dramatic changes in the orientation of the planet's ring disk. The ring system revolves around a fixed axis, so both sides of the ring disk are visible from Earth during each period in which Saturn orbits the Sun.
