Saturn Is Less Dense Than Water and Would Float
Saturn is the least dense planet in our solar system; if you could find a bathtub big enough, it would float in water.
About this fact
Saturn's average density is about 0.687 grams per cubic centimeter, while water's density is 1 gram per cubic centimeter. This means Saturn is less dense than water. Although it's a gas giant and doesn't have a solid surface to float on, this low density is a remarkable characteristic. It's primarily composed of hydrogen and helium, the lightest elements.
