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 density of Earth is 5.52 g/cm 3. This makes it the densest planet in the Solar System. The density of Io is 3.53 g/cm 3. Astronomers believe that the Moon formed when a Mars-sized object crashed into the Earth. The resulting debris from the collision collected into orbit around the Earth and became the Moon.he density of Io is 3.53 g/cm 3.
