* The Sun: The Sun is a star, a giant ball of hot gas that generates its own light and heat through nuclear fusion. It's primarily composed of hydrogen and helium, but it's not a gas giant in the sense of planets like Jupiter or Saturn.
* The Moon: The Moon is a natural satellite, a rocky body that orbits a planet. It's not made of gas and doesn't have the massive size and gravitational pull associated with gas giants.
Gas giants are massive planets composed primarily of hydrogen and helium, with trace amounts of other elements. They lack a solid surface and have very low densities compared to rocky planets. Examples include Jupiter, Saturn, Uranus, and Neptune.
