Saturn is much larger than Earth. However, it doesn't have a lot of mass for its size. So, Saturn's surface gravity is slightly less than Earth's. A person weighing 100 pounds (45 kg) on Earth would weigh 93 pounds (42 kg) on Saturn. Move the slider below to compare weights. The slider shows weight in pounds. Saturn doesn't have a solid surface. The weight is calculated as if you were standing at the top of Saturn's atmosphere.
