In the beautiful family of the eight planets, Saturn is definitely the one that loves dressing up the most! Its most famous feature is the extremely gorgeous, wide 'great ring' circling its body. Looking through a telescope, it looks just like it's wearing a dazzling, super oversized straw hat. Little Panda tells you a little secret: this great ring isn't a solid, hard board at all! It is actually made of countless sparkling ice chunks, rock fragments, and cosmic dust swirling around Saturn at high speeds, forming a shiny 'space gemstone belt.' Although some parts are thin—only a few meters deep—the ring stretches out for hundreds of thousands of kilometers. No wonder everyone praises it as the most photogenic and handsome planet in the solar system!
