Saturn -- rings aren't just for bathtubs anymore.

• Saturn is huge. It is the second largest planet in our Solar System. Jupiter is the only planet that is bigger.
• You cannot stand on Saturn. It is not like Earth. Saturn is made mostly of gases. It has a lot of helium. This is the same kind of gas that you put in balloons.
  
• Its beautiful rings are not solid. They are made up of bits of ice, dust and rock.

 

Saturn is encircled by seven major rings. In this photograph, a section of the rings is hidden by the planet's shadow. The Cassini spacecraft, launched in 1997 to study Saturn and its rings and satellites, captured this natural color image as it approached the planet in 2004.
