Question

How do the densities of the jovian and terrestrial planets compare?

Answer 1

Hello

The jovian density is $1.33~g/cm^3$, while the density of terrestrial planets is much higher. For instance, the earth's density is $5.51~g/cm^3$. The reason of this difference is in the different chemical composition: while jupiter is made of gas (mainly hydrogen), with lower density, while the terrestrial planets are made of solid and liquid, with compounds of higher density.
