giant planets
Jupiter and Saturn
Giant planets are the four largest planets in the solar system—Jupiter, Saturn, Uranus, and Neptune—distinguished from the smaller terrestrial planets by their massive size, thick gaseous atmospheres, and lack of solid surfaces.
Jupiter and Saturn are gas giants composed mainly of hydrogen and helium, while Uranus and Neptune are ice giants with substantial water, ammonia, and methane.
