Although Saturn has seven ring groups, scientists do not know exactly how many rings are around the planet. This is because the ring groups are made up of thousands of smaller rings, according to the Cool Cosmos website published by the Infrared Processing and Analysis Center.
Galileo discovered Saturn's rings in 1610, according to experts from NASA. The planet's ring system has billions of particles in a wide range of sizes. Some of the particles are tiny grains, while others are the size of mountains. These particles may be from asteroids, comets or shattered moons that disintegrated before they reached Saturn.
