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%.
Earth is the densest planet in the solar system because of its metallic core and rocky mantle. Jupiter, which is 318 more massive than Earth, is less dense because it is made of gases, such as hydrogen. Earth's mass is 6.6 sextillion ton (5.9722 x 10 24 kilograms). It volume is 1.08321 x 10 12 km.he circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole â the meridional circumference â Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid. Density, mass and volume.
