Saturn's atmosphere is mostly hydrogen and helium
Saturn has the lowest density of any planet in our solar system
Its radius is about nine and a half times that of Earth on average, making it a gas giant.
Saturn's rings are made up of ice and dust particles
Saturn's rings are the biggest and brightest.
Saturn is the only planet in the solar system with a mean density of 0.687 grams per cubic centimeter, making it less dense than water.
Saturn's interior is composed of a rocky core, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer.
The pale yellow hue of Saturn is due to ammonia crystals in its upper atmosphere.
The strength of Saturn's magnetic field is about one-twentieth that of Jupiter.
Its most notable feature is its prominent ring system, which is composed mainly of ice particles, with a smaller amount of rocky debris and dust.
By volume, 96.3% of Saturn's outer atmosphere is molecular hydrogen, and 3.25% is helium.
