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%.
The densest known material is the Element Osmium, at about 22 tonnes per cubic meter. The densest theorized material would be white dwarf/neutron star matter, which could be mâ¦illions of times denser. Of course, since it occupies no space at all, the density of a black hole's singularity is technically infinite.
