sci-fact:


Saturn is the only planet in our solar system with an average density less than that of water.&nbsp;It is&nbsp;roughly&nbsp;68.7% as dense, about the same as an apple.&nbsp;This means that if the entire planet were placed in a giant ocean, it would easily float to the top. The next runner up, Uranus,&nbsp;possesses&nbsp;nearly twice the density.&nbsp;
