Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Planets farther out into space are formed mostly of gases like hydrogen and helium. They have no hard rocky surface. They are called ____
A
Terrestrial planets
B
Minor Planets
C
Jovian Planets
D
Astroids
Explanation: 

Detailed explanation-1: -Jovian planets include Jupiter, Saturn, Uranus, and Neptune. These planets have larger sizes and masses. Jovian planets do not have solid surfaces. They are sometimes called gas giants because they are large and made mostly of gases.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter. These are also called the Jovian planets.

Detailed explanation-5: -Terrestrial planets are denser than Jovian planets. Jovian planets are rich in ammonia, hydrogen, and helium. The cores of Jovian planets are less dense.
