The planet Saturn is shown against the black background of space.  It is bright beige in color, with rings around the center.

Saturn is the sixth planet from the sun and the second biggest in our solar system. Saturn is a gas giant, which means that it doesn’t have a solid surface that a spacecraft could actually land on. Instead, it’s mostly made up of hydrogen and helium with a liquid and metal core. Saturn spins so fast that a full day lasts just under 11 hours, but it takes so long to get around the sun that one year on Saturn is equal to 29 Earth years!  

Saturn is the most famous for its rings! While Jupiter, Neptune, and Uranus all have rings, Saturn’s rings are by far the biggest and easiest to see from Earth. The rings are not actually flat discs like they appear to be in pictures, but rather, they’re made up of chunks of space debris, like ice and rocks. The pieces of ice and rock range from the size of dust to the size of buildings, and every size in between.

The sun appears on the left, and then all of the planets are shown in a line across the image.  Mercury, Venus, Earth (with Earth's moon peeking from behind), Mars, Jupiter, Saturn, Uranus, Neptune.
