The gas giants Jupiter and Saturn are primarily composed of hydrogen and helium, with thick atmospheres surrounding their dense cores. Uranus and Neptune, the ice giants, have atmospheres rich in methane, ammonia, and water, along with a mixture of hydrogen and helium. These planets have minimal solid surfaces compared to terrestrial planets, making their atmospheres a significant part of their overall structure.
