The four Jovian planets that have rings are Jupiter, Saturn, Neptune and Uranus. The planet with the most visible rings is Saturn; the other three planets have rings that are more faint and difficult to spot.

The rings of Saturn are made up of billions of particles. They vary in size from very small ice particles the size of dust to very large particles as big as mountains. There are two gaps between the rings known as the Keeler and Encke gaps. It is in these gaps where the moons of Saturn orbit this massive planet. The rings were named alphabetically in the order in which they were discovered. The most prominent rings are named C, B and A when working from the most inward ring out.
