Detailed explanation-1: -The terrestrial planets form in the area of the inner disk, which is closer to the star and heavy with dust and rocks. The gas giants, on the other hand, form in the exterior area of the disk, which is further from the star and contains condensing gas and ice.

Detailed explanation-2: -Gas giants, like Jupiter or Saturn in our solar system, are composed mostly of helium and/or hydrogen. Gas giants nearer to their stars are often called “hot Jupiters.” More variety is hidden within these broad categories.

Detailed explanation-3: -At larger masses, the planet’s ocean boils and the atmosphere becomes a dense mixture of steam and hydrogen and helium. When a planet reaches a few times the mass of Earth, the atmosphere will grow rapidly, faster than the solid part of the planet, eventually forming a gas giant planet like Jupiter.

Detailed explanation-4: -The four outer gas giant planets (Jupiter, Saturn, Uranus, and Neptune) made of frozen hydrogen, ice-water, and ocean.

Detailed explanation-5: -He believes gas giants could form as a result of instability in a star’s protoplanetary disk. “In the disk instability mechanism, the action occurs in a disk of gas and dust which is orbiting around a star, ” says Boss. “Clumps form, contracting and increasing in density to become gas giant protoplanets.”
