Compton's, 1995. They divide the mass of the Earth by the volume, which gives the average density of the material in the earth as 3.2 ounces per cubic inch (5.5 g/cm 3).. 5.5 g/cm 3. Orbits Voyage Through The Solar System. Phoenix, AZ: Software Marketing, 1989. Mean Density: (water = 1) 5.52.. 5.52 g/cm 3. Morse, Joseph Laffan.
It is hard to conceive that Saturn is made up of much more than gas based on its low density. Saturn has a density of 0.687 g/cm3. Earth, on the other hand, has a density of 5.513 g/cm3. That means that a planet that has 95 times more mass than Earth has barely 12% of its density. Saturnâs density is so low that it could float on water more easily than most boats.
