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%.
Venusâ mass is only approximately 81% of Earthâs mass, so it is not surprising that Venus is also less dense than our own planet. Venus has a density of 5.204 grams per cubic centimeter. Earth is the densest planet in our Solar System.ust like the size of the planets, the density of the planets varies widely. All of the 4 inner planets â the planets closest to the Sun â are much denser than the four outer planets. That is because the inner planets, which are also called terrestrial planets, are made up of heavy metals and rocks.
