Explanation: 

Detailed explanation-1: -The larger volume of space and lower gravity of the Sun in the giant-planet region allowed Jupiter, Saturn, Uranus, and Neptune to form like solar systems in miniature. We think each of them pulled in lots of material and had a disk of gas, dust, and ice surrounding it during formation.

Detailed explanation-2: -Perhaps no planet in our solar system resembles a miniature solar system more than Saturn. Like a silvery pearl, an icy moon crosses the face of Saturn, while two of its siblings cast shadows onto the planet. “Saturn plus its moons are like the sun plus the planets, ‘’ said Linda Spilker, Cassini’s project scientist.

Detailed explanation-3: -The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter. These are also called the Jovian planets. “Jovian planet” refers to the Roman god Jupiter and was intended to indicate that all of these planets were similar to Jupiter.
