This planet is mainly recognized due to its size as it is one of the biggest just after Jupiter and especially due to its visible ring system. The ring system of Saturn is composed of ice, debris, rocks and other materials that surround the planet and are visible, different to the ring systems in Uranus, Jupiter, and Neptune that are less dense or dark and therefore cannot bee seen.
