This is a drawing showing the composition of the interior of Jupiter.

What the inside of Jupiter is made of

The composition of Jupiter's interior is mostly the simple molecules hydrogen, in the form of liquid.

Under the cloud layers, when the environment is just right, the hydrogen of which Jupiter is made changes to liquid hydrogen. The liquid hydrogen gradually changes further to liquid metallic hydrogen.

The core of Jupiter is made out of rock and metal.
