Learn about saturn's rings, moons, structure, atmosphere, and more from nasa's science website. The full set of rings, imaged on 19 july 2013 as saturn eclipses the sun from the vantage of the cassini orbiter, 1.2 million kilometres (3⁄4 million miles) distant Saturn has the most extensive and complex ring system of any planet in the solar system Known for its stunning rings, saturn is a gas giant made mostly of hydrogen and helium. Saturn is often believed to be the only planet in the solar system with rings — but that's not true All four giant planets of the solar system, saturn, jupiter, uranus and neptune, the asteroids chariklo and chiron, the dwarf planets haumea and quaoar, and hypothetically, saturn’s moon rhea, have rings.
A planet’s moons can also influence its ring system For example, jupiter has rings just like the other gas giants, but its rings are smaller and fainter than saturn's.
