Saturn
Discover amazing facts about Saturn, the spectacular ringed planet and the most beautiful world in our solar system
Saturn's magnificent rings are made of billions of ice and rock particles
Saturn is often called the most beautiful planet in our solar system because of its spectacular rings! These amazing rings make Saturn look like a giant cosmic jewel floating in space. Saturn is the second-largest planet after Jupiter and is also a gas giant made mostly of hydrogen and helium. What makes Saturn really special is that it's less dense than water - which means if you could find an ocean big enough, Saturn would actually float!
Saturn's famous rings aren't solid like a hula hoop - they're made of billions and billions of chunks of ice and rock, ranging in size from tiny pebbles to pieces as big as houses. These ring particles orbit around Saturn like a giant cosmic dance, and scientists think the rings might be pieces of moons or comets that got too close to Saturn and were broken apart by the planet's powerful gravity.
The most successful mission to Saturn was NASA's Cassini spacecraft, which spent 13 incredible years studying the ringed planet from 2004 to 2017. Cassini took thousands of stunning photos of Saturn's rings and discovered that they're much more complex than scientists originally thought. The mission also dropped a small probe called Huygens onto Saturn's moon Titan, giving us our first close-up look at this mysterious world with its thick atmosphere and liquid lakes.
NASA is currently planning a mission called Dragonfly that will send a helicopter-like drone to explore Titan in the 2030s! This amazing flying robot will hop from place to place on Titan's surface, studying its strange chemistry and looking for signs that life could exist there. Scientists are also interested in Saturn's moon Enceladus, which might have a hidden ocean under its icy surface where life could potentially survive.
