Detailed Solution

The given statement is true.
Concept: The outermost planets of our solar system are known as Jovian planets. There are four Jovian planets in our solar system. The word "Jovian" refers to Jupiter, the biggest of the outer planets.
Outside of our Solar System's "Frost Line," where flammable substances like water, ammonia, and methane tend to freeze, there are four sizable planets. These planets—Jupiter, Saturn, Uranus, and Neptune—have different sizes, masses, and compositions, yet they all have qualities in common that distinguish them from the inner Solar System's terrestrial planets.
These are the traits of the four Jovian planets:
They are referred to as the Gas Giants because they are mostly composed of hydrogen and helium gas with varying amounts of heavier components. They are made of gases and are less dense than terrestrial planets.
They have several moons, and their mass makes them gravitationally more powerful.
They also wear rings.
a gas giant's surface is absent, at least in comparison to a terrestrial planet. When describing temperatures and air pressure, scientists refer to the "surface" of a gas giant as the region where atmospheric pressure exceeds one bar (the pressure found on Earth at sea level) .
In light of this, the four Jovian plan
ets are Jupiter, Saturn, Uranus, and Neptune
Hence,the given statement is true.
