Hydrogen and Helium

GAS GIANTS

The gas giants in our Solar System are Jupiter and Saturn, both characterized by thick atmospheres, strong magnetic fields, and a lack of a well-defined solid surface. These planets often have a rocky or metallic core, surrounded by deep layers of gas and liquid.

It mostly hydrogen and helium, with trace amounts of methane, ammonia, and water vapor. Their dense atmospheres create layers of different gases under immense pressure.

Rings and moons
Both Jupiter and Saturn have intricate ring systems (Saturn’s being the most prominent) and numerous moons, including some with unique geological features or potential subsurface oceans.
