According to NASA, it takes Saturn 10 hours and 15 minutes to rotate or spin on its axis. However, it takes Saturn 30 Earth years to orbit the sun due to its distance from the center of the solar system.
The gaseous composition of Saturn combined with its fast rotation make for flat poles, which result in an easily visible equatorial bulge. Saturn is made of mostly hydrogen and helium gases, just like Jupiter, but it is twice as far away from Earth as Jupiter, which is why it appears so small when viewed from Earth. Saturn's mass is only 30 percent of Jupiter's mass, and Saturn has the lowest density of any planet in the solar system.
