gas planet
Definition
A gas planet is a planet that is made mostly of gas. Gas planets do not have a solid surface, but they have a thick atmosphere that is made up of hydrogen, helium, and other gases.
Gas planets are very large. Jupiter is the largest planet in our solar system, and it is even larger than some stars! Saturn, Uranus, and Neptune are also gas planets.
Gas planets are very hot inside. The temperature at the centre of Jupiter is about 24,000 degrees Fahrenheit! The heat from the centre of the planet causes the gas to rise to the top, where it cools and falls back down. This creates the winds that we see on gas planets.
Gas planets are very important in our solar system. They help to keep the planets in their orbits, and they also help to protect us from harmful solar radiation.
