According to Universe Today, the most distinct similarity between the Earth and Saturn is gravity. While the mass of the two planets differs incredibly, the gravity of Saturn works in the same way as the gravity of Earth. Saturn does not have a solid surface. However, if one were able to walk on Saturn, gravity would hold one to the surface just as it does on Earth.
Beyond gravity, there are no real similarities between Saturn and Earth, only stark contrasts, according to Universe Today. The Earth is the densest planet in the solar system, while Saturn is the least dense, making the Earth eight times more dense than Saturn. Saturn has rings around it, while the Earth does not. It takes 24 hours to complete a day on Earth, and a day on Saturn is 10 hours and 32 minutes long. One year on Saturn takes 30 years to complete compared to the Earth's year.
Saturn's equatorial diameter is 9.5 times the diameter of Earth, making it the second largest planet, according to Universe Today. The surface area of Saturn measures in at 83 times that of Earth, and its volume is 764 times the volume of Earth. According to NASA, Saturn's atmosphere is made up of helium and hydrogen, while the Earth's atmosphere is made of nitrogen and oxygen.
