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%.
Mercury is the only other planet that has a density similar to Earthâs. Venus is the only planet which is similar in more ways then one. Because of this, Venus has been referred to as Earthâs twin. The diameter of Venus is 7,521 miles or 12,104 kilometers.This is close to the 7,926 miles or 12,756 km diameter of the Earth. Venusâ mass is roughly 80 percent that of Earthâs. 95% of Earthâs density is the density of Venus. The force of gravity of both planets is similar.his is close to the 7,926 miles or 12,756 km diameter of the Earth.
