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%.
Combined with its size and mass, Mercury has a surface gravity of 3.7 m/s 2, which is the equivalent of 0.38 of Earthâs gravity (aka. 1 g). Density of Venus: The second planet from our Sun, as well as the second-closest terrestrial planet, Venus has a mean density of 5.243 g/cm 3. Again, this is very close to Earthâs own density.
