Saturn, the sixth planet from the Sun, is famous for its spectacular ring system. These rings are not solid bands; instead, they are billions of tiny particles that (21) __________ the planet. While they look solid and bright from Earth, they are actually incredibly thin and wide, stretching out for thousands of kilometers.

For a long time, astronomers wondered what these rings were made of. We now know they are a complex system consisting mostly of water ice. It's estimated that 99.9% of the material is pure ice. The remaining tiny fraction is composed of rock and dust. (22) __________, their high ice content is what makes them so bright and reflective.

The particles that make up the rings vary greatly in size. Some are as tiny as grains of dust, while others are as large as a house or even a small mountain. These countless pieces are not a single object but are made up of individual moonlets. They are constantly colliding and breaking apart, creating a dynamic environment with pieces (23) __________ in size from microscopic to massive.

The origin of the rings is still debated. One leading theory suggests they are the remains of a moon or comet that was torn apart by Saturn's gravity. A scientist once reported that the rings (24) __________ younger than the planet itself. If a spacecraft could fly through the gaps in the rings, it would have to navigate through this field of icy debris very carefully.

From a distance, Saturn's rings appear to be a magnificent, unified structure. However, each individual particle is like a drop in the ocean in the vastness of space. Understanding their composition helps us appreciate not just the beauty of Saturn, but also the complex and dynamic processes that shape our solar system.
