Question

What are the four Jovian planets and what are their characteristics ?

Answer 1

Hint: Jovian Planets are planets in our solar system's outer parts. In our solar system, there are four Jovian planets. Jupiter is known to be the largest of the Outer Planets, inspired by the name Jovian.

Complete answer:
Four large planets exist outside our Solar System's "Frost Line" – the area where volatiles like water, ammonia, and methane tend to freeze. While the size, mass, and composition of these planets – Jupiter, Saturn, Uranus, and Neptune – vary, they all share similar characteristics that set them apart from the terrestrial planets in the inner Solar System.

Characteristics of the four Jovian planets are:
-They are known as the Gas Giants mainly consisting of hydrogen and helium gas with differing degrees of heavier elements. They are also less dense than terrestrial planets and they are composed of gases.
-They have a lot of moons and their mass gives them more gravitational pull.
-They have rings as well.
-A lack of a surface of gas giants, at least as opposed to terrestrial planets. In both cases, scientists describe a gas giant's "surface" as the area where atmospheric pressure reaches one bar (for the purposes of defining temperatures and air pressure) (the pressure found on Earth at sea level).

Therefore, the four Jovian planets are Jupiter, Saturn, Uranus, and Neptune.

Note: Pluto is known as a Jovian planet because of its location in the solar system, but it is much smaller than terrestrial planets. Its overall density is similar to that of the giant outer (Jovian) planets, despite its size being smaller than terrestrial planets.
