The Interiors of the Giants of the Solar System

The four Jovian planets in the Solar System

The giants of our solar system, other than the Sun of course, are quite different from the terrestrial planets whether it comes to the atmospheres, the surfaces, size, or other planetary features. One key difference is the interior of these giant planets. Terrestrial planets, for context, have a very dense core followed by a rocky mantle and ultimately a thin crust (or surface). When it comes to the giants, or Jovian, planets, the interiors are similar in that they have layers but the compositions are quite different.

The interiors of the four Jovian planets

As you can see in this visual, the layers are present but the compositions are what make these planets distinct from the terrestrials. The cores consist of rock, metals, and different gases. Jupiter and Saturn are similar to one another while Uranus and Neptune resemble one another more.
Jupiter’s and Saturn’s cores are surrounded by layers of hydrogen transforming from a solid to a liquid to a gaseous form. What we see from Earth are the surfaces of the planets which are primarily clouds of gas swirling around as the planets rotate. Uranus’ and Neptune’s inner cores consist of rock and metals while the outer core is made of water, methane, and ammonia. The core is then surrounded by gaseous hydrogen covered by clouds that we see from Earth.
I just wanted to share this with you all since we tend to hear so much about the terrestrial planets. Hopefully, you learned a little something about the Jovian planets and will dig deeper to maybe understand them more.
