Fact Sheet
Longer Days?
A day on the planet Saturn, shown as a golden crescent in this view from the Cassini spacecraft, may be a few minutes longer than scientists have thought. Cassini observations show that Saturn's "day" is about eight minutes longer than shown by earlier space- and ground-based measurements. Saturn's rings form a thin horizontal line across the middle of the picture, and they cast dark shadows over the planet's northern hemisphere. [Credit: NASA/JPL/SSI]
