11. Why Do Planets Have Rings?

Country Available: Canada

Bob MacDonald

Fly through the rings of Saturn aboard the Cassini spacecraft and have a snowball fight among the billions of particles circling the most beautiful planet. Saturn is not the only planet with rings, all the giant worlds in our solar system have them and they’re all different. Some rings are thin and black as charcoal, another is orange. The Earth doesn’t have a ring today but long ago a brilliant ring did surround our planet. It eventually turned into our moon! Find out how rings form, why only some planets have them and join the search to find other ringed planets around other stars.
