Detailed explanation-1: -What is a gas giant? A gas giant is a large planet mostly composed of helium and/or hydrogen. These planets, like Jupiter and Saturn in our solar system, don’t have hard surfaces and instead have swirling gases above a solid core.
Detailed explanation-2: -At larger masses, the planet’s ocean boils and the atmosphere becomes a dense mixture of steam and hydrogen and helium. When a planet reaches a few times the mass of Earth, the atmosphere will grow rapidly, faster than the solid part of the planet, eventually forming a gas giant planet like Jupiter.
Detailed explanation-3: -The four outer gas giant planets (Jupiter, Saturn, Uranus, and Neptune) made of frozen hydrogen, ice-water, and ocean.
Detailed explanation-4: -The planet Jupiter, Saturn, Uranus and Neptune are sometimes called the Gas Giants because so much of the mass of these planets consists of a gaseous atmosphere.
