Uncompressed Density The density a planet would have if its gravity did not compress it. Uniform circular motion ...
43 g/cm³, only slightly less than Earth's density. If the effect of gravitational compression were to be factored out, the materials of which Mercury is made would be denser, with an uncompressed density of 5.3 g/cm³ versus Earth's 4.4 g/cm³.
