* Hydrogen (H2): Around 96.3%

* Helium (He): About 3.25%

These are the two dominant gases, making up almost the entire atmosphere.

There are also trace amounts of other gases, including:

* Methane (CH4): Responsible for Saturn's yellowish hue and contributes to the formation of its iconic rings.

* Ammonia (NH3): Forms clouds in the upper atmosphere.

* Water (H2O): Exists as ice crystals in the deeper layers of the atmosphere.

* Phosphine (PH3): A rare and intriguing molecule detected in Saturn's atmosphere.

* Hydrocarbons: Including ethane, acetylene, and propane, which are formed by the interaction of sunlight and methane.

Note: The precise composition of Saturn's atmosphere can vary with altitude and location.
