Saturn

Saturn is one of the Giant Planets, too. It is the second largest Planet in our Solar-System. Saturn also is striped like Jupiter. But the stripes are neater than Jupiter. Jupiter’s stripes goes up and down like a wave that wiggles. Saturn’s stripes are straight.



Saturn has the biggest & thickest rings in our Solar-System. Its Rings makes everybody to their favourite Planet to watch out the Telescope. People in the past thought that Saturn has only one Ring. Then they discovered that there was a spit into three parts. So, Saturn has three Rings. The three rings are called the Cassini Division, Encke Division and the third one is the one that is the furthest from the Planet, separated with the other Rings and is called the F-Ring. The F-Ring is separated to the other Rings because there are one or two Moons blocking it. Those two Moons are called Prometheus and Pandora. They orbit the F-Ring around Saturn. The two Planets are called “Shepherd Satellites”, because they keep the F-Ring separated from the other two. The Cassini Division is named after the famous Italian-French Astronomer called Giovanni Cassini (1625 - 1712, because he discovered it. I don’t know the name of the other Astronomer for Ring Encke but, I know it must be First Name and then Encke for Last Name. The Rings are mostly made of Ice and Rocks. Saturn’s poles are more flattened than Jupiter’s. Not because it spins faster than Jupiter, it doesn’t. Only a few people know why. Saturn is not much smaller than Jupiter, but the Mass is only one third of Jupiter. This means that Saturn is lighter than water – if you would drop it into an ocean that is bigger than the Planet, it would float. Titan Saturn’s biggest Moon has the thickest atmosphere of any Moon in our Solar-System. It may even have oceans beneath the orange clouds.
