Average Densities

Here are the planets of the solar system arranged in order of increasing average density:

1. Saturn - 0.69 g/cm³
2. Uranus - 1.27 g/cm³
3. Jupiter - 1.33 g/cm³
4. Neptune - 1.64 g/cm³
5. Mars - 3.93 g/cm³
6. Venus - 5.24 g/cm³
7. Mercury - 5.427 g/cm³
8. Earth - 5.52 g/cm³

Note that the densities listed above are approximate values and are given in grams per cubic centimeter (g/cm³). The average density of a planet depends on its size, composition, and internal structure.
