SOLAR SYSTEM

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: -Neptune does not have a solid surface. Its atmosphere (made up mostly of hydrogen, helium, and methane) extends to great depths, gradually merging into water and other melted ices over a heavier, solid core with about the same mass as Earth.

Detailed explanation-3: -Jupiter to Neptune are called giant planets or Jovian planets.

Detailed explanation-4: -The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter. These are also called the Jovian planets. “Jovian planet” refers to the Roman god Jupiter and was intended to indicate that all of these planets were similar to Jupiter.

Detailed explanation-5: -Gas giants are large planets composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system-Jupiter, Saturn, Uranus and Neptune-together make up a group known as the Jovian planets, according to the University of Colorado at Boulder (opens in new tab).
