Gas giants are primarily composed of hydrogen and helium, which are the most abundant elements in the universe. In addition to these gases, they also contain small amounts of other elements and compounds, such as methane, ammonia, and water vapor.

Size and Density

Gas giants are much larger in size compared to the terrestrial planets. They have a low density, which means they are not as compact as rocky planets. Despite their huge size, gas giants have relatively low mass compared to their volume.

Atmosphere

The atmosphere of gas giants is characterized by thick layers of gas, with no solid surface. The atmosphere is divided into different layers, with varying temperatures, pressures, and compositions. The colorful bands and swirling storms, such as Jupiter's Great Red Spot, are prominent features of their atmospheres.

Rings and Moons

Some gas giants, like Saturn, have impressive ring systems made up of icy particles and rocky debris. These rings are thought to be formed from the gravitational interactions between the planet and its moons. Gas giants also have a diverse array of moons, each with unique features and characteristics.

Magnetosphere

Gas giants have strong magnetic fields that extend far into space, creating a protective magnetosphere around the planet. This magnetosphere interacts with the solar wind and influences the behavior of the planet's atmosphere and its moons.
