They are both made up of gases of various sorts, but none breathable by humans. Jupiter and Saturn have very small rocky centers the size of several Earths.

Jupiter is composed of mainly hydrogen, some helium, and traces of nitrogen, ammonia ice, and water ice.

Saturn's composition is very similar, but it also has some methane ice in it.

The pressure inside these gas giants is so great that the hydrogen is in the form of a solid metal down very, very deep.

Which planets are mostly just a ball of gas?

Jupiter and Saturn are mostly made up of gas, with no solid surface. They are known as gas giants because their composition is primarily hydrogen and helium, with some other trace elements.


Which moon has a thick atmosphere made mostly of nitrogen in Jupiter?

Titan, a moon of Saturn, has a thick atmosphere mainly composed of nitrogen. Jupiter's moon Ganymede has a thin atmosphere made up of oxygen.


What is the Name for planets whose atmosphere is made up of mostly gases?

Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.


Which planet is made mostly of gases?

These are the four outer gas giant planets; Jupiter, Saturn, Uranus and Neptune.This is the view of the older text books. However, since the voyager flybys, it was detected that Uranus and Neptune had different chemical composition than Jupiter and Saturn and they contained more ice. For that reason, they are now considered Ice Giants and not Gas Giants.JupiterJupiterJupiter, Saturn, Neptune and Uranus are referred to as the "Gas Giants"due to their being comprised of non-rocky materials.Of these four, Jupiter and Saturn are comprised mostly of gases.-S.M.


What planets have gases?

Why is Saturn almost as big as Jupiter despite its smaller mass?

Although Saturn has a smaller mass than Jupiter, it is nearly as big because it is less dense. Saturn is made mostly of hydrogen and helium, which are less dense than the materials that make up Jupiter, allowing Saturn to be larger in size despite less mass.
