Saturn is one of the gassy planets and is huge compared to the size of Earth. Saturn has a diameter of 120,536km much bigger than Earth. Earth, however only has a diameter of â¦ 12,756km.
Saturn is the sixth planet in our solar system. While Saturnâs rings seem to be the most noticeable, there are other planets that have rings. Neptune, Jupiter and Uranus all have rings around them, but you have to get a powerful telescope to actually see them. The rings around Saturn are the largest and the brightest of all of the planets, spanning 175,000 miles! To give you an idea of how big that is, it is almost three quarters of the distance between the earth and the moon. They may be wide, but they are also very thin: only 30 to 300 feet thick.
