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%.
If you're talking about the entire planet together, then of all the planets in our solar system, earth is the most dense. Rock planets are obviosly denser than gas giants, and the largest rock planet is earth, making it have the most gravity, which causes it to be the most condensed and have the highest density. The Earth is the densest planet in the Solar System overall. It has a density of about 5.515 times that of water. However, it is only the densest because it is made of rocky material AND massive enough for that material to be compressed more under its own gravity and internal pressure. If it were not for gravitational compression, Mercury would actually be denser than the Earth.
