They are called gas giants, actually. They are called that, because they have a very thick atmosphere and the core is so deep below the 'surface' of the atmosphere that we cannot see the core.
The solar system
The planets are made out of gas.
These four planets are known as the 'Gas Giant' planets.
The outer planets are Gas Giants, also known as Jovian planets.

No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
The outer planets in our solar system—Jupiter, Saturn, Uranus, and Neptune—are often referred to as the "gas giants" because they are primarily composed of hydrogen and helium gas.
The jovian planets (Jupiter, Saturn, Uranus, and Neptune) are named after the Roman god Jupiter, who is the king of the gods. This naming convention reflects the grand and powerful nature of these gas giant planets, similar to the grandeur of the king of the gods in Roman mythology.
Jupiter, Saturn, Uranus, and Neptune
The four outer, or gas planets are Jupiter, Saturn, Uranus and Neptune. They are mainly made up of Hydrogen and Helium gas. They are also much larger than the Earth or the other three inner planets, so are referred to as gas giants.
