SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -Inspection of the blackbody temperatures in Figure 1 suggests that the planets beyond the orbit of Mars, specifically Jupiter, Saturn, Uranus, and Neptune, would be unlikely to support life, since the temperatures are extremely cold. These giant planets are not only extremely cold, but are totally different than Earth.

Detailed explanation-3: -Jupiter, Saturn, Uranus, and Neptune are the four largest planets in our solar system. They are also known as the outer planets because they exist beyond the asteroid belt between Mars and Jupiter.

Detailed explanation-4: -Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them.

Detailed explanation-5: -While Saturn’s bright rings are the most visible and well known, fainter and darker rings have been seen around Jupiter, Uranus, and Neptune. The Jovian planets also are distinctive for having many moons. Saturn and Jupiter each have more than 60 moons, Uranus has more than 20, and Neptune has more than 10.

Detailed explanation-6: -Within the Solar System, four Jovian planets exist – Jupiter, Saturn, Uranus and Neptune. A planet designated as Jovian is hence a gas giant, composed primarily of hydrogen and helium gas with varying degrees of heavier elements.
