Strange Astronomy Facts
1) Saturn would float if you put it in a large enough body of water. Although Saturn is very large, as well as being the second largest planet in our Solar System, it is less dense than water because it is mostly made up of gases. As a result, it is lighter than water and hence would float on water. It is the only planet in our solar system that is less dense than water.
