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%.
Density of Earth: Earth has the highest density of any planet in the Solar System, at 5.514 g/cm3. This is considered the standard by which other planetâs densities are measured. In addition, the combination of Earthâs size, mass and density also results in a surface gravity of 9.8 m/sÂ².
