Where does the word gas giant come from?

The term "gas giant" is used to describe a type of planet in our solar system that has a relatively small, rocky core enveloped by a thick atmosphere composed mainly of gases such as hydrogen, helium, and methane. These planets, which include Jupiter, Saturn, Uranus, and Neptune, are much larger than Earth and have no solid surface due to the thickness of their atmospheres. The name "gas giant" originated in the 19th century when astronomers believed that these planets were primarily composed of gases. However, subsequent scientific discoveries revealed their true nature with solid cores that were enveloped by dense atmospheres composed of gases. Today, the term "gas giant" is still used to describe these unique and fascinating worlds in our solar system.
