Why do some planets have rings?
|
The planets Jupiter, Saturn, Uranus, and Neptune have rings around their equators made from chunks of ice, dust, or boulders. These particles were either left over when the planets were formed, or they may be the remains of broken-up moons. | | Saturn's rings are visible from Earth with a telescope. |
