By matching the Measured Density to the Calculated Density, you are likely to find values similar to the following: Earth has a core filling about 65% of its interior. Venus: 65%, Mars: 40%, Mercury: 80%, The Moon: 40%.
Saturn, much like Jupiter, is thought to have a loose core made up of relatively little rock and some metals. 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/cm 3. Earth, on the other hand, has a density of 5.513 g/cm 3. That means that a planet that has 95 times more mass than Earth has barely 12% of its density.
