Saturn
Saturn is the sixth planet from the Sun and the second-largest planet in our solar system.
Adorned with thousands of beautiful ringlets, Saturn is unique among the planets. It is not the only planet to have rings – made of chunks of ice and rock – but none are as spectacular or as complicated as Saturn's.
Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium.

10 Need-to-Know Things About Saturn
#1 - A Colossal Planet
Nine Earths side by side would almost span Saturn’s diameter. That doesn’t include Saturn’s rings.
#2 - In Dim Light
Saturn is the sixth planet from our Sun (a star) and orbits at a distance of about 886 million miles (1.4 billion kilometers) from the Sun.
#3 - Short Day, Long Year
Saturn takes about 10.7 hours (no one knows precisely) to rotate on its axis once—a Saturn “day”—and 29 Earth years to orbit the sun.
#4 - Gas Giant
Saturn is a gas-giant planet and therefore does not have a solid surface like Earth’s. But it might have a solid core somewhere in there.
#5 - Hot Air
Saturn's atmosphere is made up mostly of hydrogen (H2) and helium (He).
#6 - Mini Solar System
Saturn has 53 known moons with an additional 29 moons awaiting confirmation of their discovery—that is a total of 82 moons.
#7 - Glorious Rings
Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them.
#8 - Rare Destination
Few missions have visited Saturn: Pioneer 11 and Voyagers 1 and 2 flew by; But Cassini orbited Saturn 294 times from 2004 to 2017.
#9 - Lifeless Behemoth
Saturn cannot support life as we know it, but some of Saturn's moons have conditions that might support life.
#10 - Add a Dash of Earth
About two tons of Saturn’s mass came from Earth—the Cassini spacecraft was intentionally vaporized in Saturn’s atmosphere in 2017.
