* Jupiter: 1.33 g/cm³
* Saturn: 0.69 g/cm³ (the lowest density of all planets in the solar system)
* Uranus: 1.27 g/cm³
* Neptune: 1.64 g/cm³
Key takeaways:
* Lower density than water: Notice that the densities of all the Jovian planets are less than the density of water (1 g/cm³). This is why they're often described as "gas giants," although they actually contain a significant amount of heavier elements like hydrogen and helium in their interiors.
* Gradual increase: The densities of the Jovian planets generally increase with distance from the Sun. This is likely due to the increasing pressure and temperature in the interiors of the planets further out.
* Composition matters: While the Jovian planets are primarily composed of hydrogen and helium, they also contain heavier elements like methane, ammonia, and water. The exact composition and distribution of these elements contribute to the slight variations in their densities.
It's important to remember that these are just average densities. The internal structure of the Jovian planets is complex, with density varying significantly from the outer atmosphere to the core.
