SOLAR SYSTEM

Detailed explanation-1: -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-2: -Gas Giant. Saturn is a gas-giant planet and therefore does not have a solid surface like Earth’s. But it might have a solid core somewhere in there.

Detailed explanation-3: -As a gas giant, Jupiter doesn’t have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn’t be able to fly through unscathed either.

Detailed explanation-4: -Neptune, like Uranus, is an ice giant. It’s similar to a gas giant. It is made of a thick soup of water, ammonia, and methane flowing over a solid core about the size of Earth. Neptune has a thick, windy atmosphere.

Detailed explanation-5: -Uranus is an ice giant (instead of a gas giant). It is mostly made of flowing icy materials above a solid core.

Detailed explanation-6: -This is why they are called gas giants: They are mostly gaseous, with very little rock and ice. Uranus and Neptune are composed of some hydrogen and helium, but they also contain heavier elements such as oxygen, carbon, nitrogen, and sulfur.
