So Jupiter's interior would resemble that of Neptune and Uranus, which appear to have a rocky core surrounded by icy hydrogen and helium, but without the gas envelope of Jupiter and Saturn. The large, rocky core implies that as Jupiter and other giant gas planets formed 4.5 billion years ago, they grew through the collision of small rocks that formed cores that captured a huge atmosphere of hydrogen and helium.
