WHAT'S IT MADE OF?

Saturn is one of the Gas Giants like Jupiter. Saturn is made of hydrogen and helium - just not as much helium as Jupiter. It is covered in an ocean of hydrogen. Below this, is liquid metallic hydrogen, then a big rock center (bigger than Jupiter's). Saturn doesn't have as much liquid metallic hydrogen as Jupiter does, so it doesn't have as strong of a magnetic field. (Saturn is not as strong of a magnet as Jupiter.)

CAN I LIVE THERE?

Definitely not! Just like Jupiter, there's no surface to stand on... You'd just have to swim around in an ocean of liquid hydrogen. But the gravity on Saturn is so strong that you'd sink anyway. There's no oxygen to breathe or water to drink.

HOW FAST A ROCKET TO GO TO GET OFF THIS THING?

To escape Saturn's gravity and get out into space, a rocket has to travel at a speed of 79,600 mph or 35.6 km/sec. That's about 1225 times faster than your parents are allowed to drive on a highway!

THE MOONS.

Saturn has 18 known moons and scientists think there may be 12 more! Maybe you'll be the one to find them for sure!

Here are the 18 (the year they were discovered is after each one): Pan (1990), Atlas (1980), Prometheus (1980), Pandora (1980), Epimetheus (1980), Janus (1966), Mimas (1789), Enceladus (1789), Tethys (1684), Telesto (1980), Calypso (1980), Dione (1684), Helene (1980), Rhea (1672), Titan (1655), Hyperion (1848), Iapetus (1671), and Phoebe (1898). Whew!

Here's a good question for you... By looking at the discovery dates for the moons, can you figure out which ones are the smallest? (The answer is at the bottom of the page.)

The very coolest (not temperature!) of Saturn's moons is Mimas. It looks just like the Death Star from Star Wars!! (picture)

OTHER COOL INFO.

The coolest thing about Saturn is its set of rings! They're not solid rings like the ones you wear on your fingers. They're kind of like Saturn's own little asteroid belt. The rings are made up of millions and millions of chunks of rock and ice. These chunks range in size from only 1 cm to 5 m (5 m is only about 16 feet - not very big). The rings, themselves, are not very thick - only about 20 meters.[b]
