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%.
Mercuryâs mean density is the second-highest in the Solar System, which is estimated to be 5.427 g/cm 3 â only slightly less than Earthâs density of 5.515 g/cm 3.However, if the effects of gravitational compression â in which the effects of gravity reduce the size of an object and increases its density â then Mercury is in fact more dense than Earth, with an uncompressed density of 5.3 g/cmÂ³ compared to Earthâs 4.4 g/cmÂ³.
