SOLAR SYSTEM

Detailed explanation-1: -Lesson Summary. The four outer planets-Jupiter, Saturn, Uranus, and Neptune-are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. All of the outer planets have numerous moons, as well as planetary rings made of dust and other particles.

Detailed explanation-2: -The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter. These are also called the Jovian planets.

Detailed explanation-3: -So, the simple answer to this question (why gas giants occupy the outer solar system?) is that their cores were once other rocky planets but because they got extra time to attract material from the nebula, their outer crust mostly has gases, hence Gas Giants.

Detailed explanation-4: -The four outer planets have longer orbits, faster spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.

Detailed explanation-5: -The Jovian Planets. From top: Jupiter, Saturn, Uranus and Neptune. Jupiter, Saturn, Uranus, and Neptune are known as the Jovian (Jupiter-like) planets, because they are all gigantic compared with Earth, and they have a gaseous nature like Jupiter’s–mostly hydrogen, with some helium and trace gases and ices.
