English: This sequence of simulated views 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.
(Note: If viewed with a parallel view stereo technique, this set of images provides a pretty plastic 3D effect to the viewer.)

These views demonstrate the 29 year period for oppositions of Saturn and the dramatic changes in the appearance of the rings. Saturn's rings stay on a fixed axis, and we see the rings from both sides over one 29 year orbit of Saturn around the Sun. Credi
