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%.
Because Mercury is so close to the sun, it is almost impossible to see it without the aid of a telescope. At 5.427 g/cmÂ³, Mercury has the second largest density in the Solar System. It is only slightly denser than Earth. Its density is the biggest thing in common that Earth and Mercury share. Mercuryâs mass is considerably smaller than that of Earthâs. Because of this the pull of gravity from Mercury is considerably lighter than that of the pull of gravity on Earth.
