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%.
Beneath that, where the planetâs hydrogen are in a liquid state, the density rises to roughly 0.5 g/cmÂ³ and increases to 1 g/cmÂ³ at the boundary with the layer composed of metallic hydrogen. The layer metallic hydrogen, meanwhile, has an estimated density of 4 g/cmÂ³ â i.e. around the same as Mars.
