Detailed explanation-1: -The four outer planets have longer orbits, faster 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-2: -All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
Detailed explanation-3: -Planets are round and opaque celestial bodies that revolve around the sun in a fixed orbit. Planets rotate around their own axis. Planets also revolve around the sun. Planets are not self-luminous like stars.
