Saturn rotates once every 10 hours and 42 minutes. Like Jupiter, this rapid rotation causes significant equatorial bulging — Saturn is the most oblate (flattened) planet in the Solar System, with an equatorial diameter 10% wider than its polar diameter.
Saturn's year lasts 10,759 Earth days — about 29.4 Earth years. Its iconic rings, made of ice and rock ranging from tiny grains to objects the size of houses, orbit at different speeds: inner rings complete an orbit in hours while outer rings take days.
Frequently Asked Questions
How long is a day on Saturn?
Saturn rotates once every 10 hours 42 minutes, making its day roughly 2.25 times shorter than Earth's.
How long is a Saturn year?
Saturn takes 10,759 Earth days (about 29.4 Earth years) to complete one orbit of the Sun.
Why is Saturn so flat?
Its rapid 10.7-hour rotation creates centrifugal force that pushes mass outward at the equator, making it the most oblate planet in the Solar System.
