SOLAR SYSTEM

Detailed explanation-1: -Answer and Explanation: Gas planets are bigger than terrestrial planets because they are older and more massive. They have more gravity which causes them to condense their particles into a denser object.

Detailed explanation-2: -The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.

Detailed explanation-3: -For example, the sizes of the inner planets are much smaller than those of the outer planets. This is because the outer planets are in a gaseous state while the inner planets are solid and more compact. Consequently, the density of the inner planets is greater than that of the outer planets.

Detailed explanation-4: -As a terrestrial planet, the Earth is much smaller than the gas giants. In comparison, Jupiter’s diameter is roughly 11 times that of the Earth. Saturn is also bigger by more than nine times while Uranus and Neptune measure around four times across.
