* Jupiter: The largest planet in our solar system, composed mainly of hydrogen and helium.
* Saturn: Known for its prominent ring system, Saturn is also primarily composed of hydrogen and helium.
* Uranus: This ice giant has a thick atmosphere primarily composed of hydrogen and helium, but also includes methane, which gives it its blue color.
* Neptune: Similar to Uranus, Neptune is also an ice giant with a thick atmosphere of hydrogen, helium, and methane.
These planets are often referred to as gas giants or Jovian planets. It's important to note that while they are primarily composed of gas, they likely have a solid core deep within.
