SOLAR SYSTEM

Detailed explanation-1: -In our solar system, gas giants are much bigger than terrestrial planets, and they have thick atmospheres full of hydrogen and helium. On Jupiter and Saturn, hydrogen and helium make up most of the planet, while on Uranus and Neptune, the elements make up just the outer envelope.

Detailed explanation-2: -These planets are much larger than the inner planets and are made primarily of gases and liquids, so they are also called gas giants or Jovian planets. The gas giants are made up primarily of hydrogen and helium, the same elements that make up most of the Sun.

Detailed explanation-3: -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-4: -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).

Detailed explanation-5: -The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful. The cores accreted rapidly into large clumps of ice and rock. Eventually, they got so large, they captured a large amount of hydrogen and other gasses from the surrounding nebula with their enormous gravity.
