Saturn
Saturn and its spectacular rings, in a natural-color composite of 126 images taken by the Cassini spacecraft on October 6, 2004. The view is directed toward Saturn's southern hemisphere, which is tipped toward the Sun. Shadows cast by the rings are visible against the bluish northern hemisphere, while the planet's shadow is projected on the rings to the left.
Saturn experiences seasons because its rotational axis is tilted substantially—by 26.7°—relative to its orbital plane. This tilt is similar to that of Earth, causing different hemispheres to receive varying amounts of sunlight as the planet orbits the Sun.12
Because of this axial inclination, Saturn undergoes seasonal changes throughout its year, which lasts approximately 29.45 Earth years. Consequently, each individual season on Saturn persists for more than seven years. This tilt also dictates the appearance of Saturn's rings from Earth, as the angle at which they are presented to observers cycles over a 30-year period.1
