Question

How are the inner and outer planets characterized?

Answer 1

Answer: 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.

Step-by-step explanation:

Answer 2

The outer planets are much larger than the inner planets and are almost entirely composed of different gases. Many of the inner planets are rocky and hot, due to their close proximity to the sun. Meanwhile, the outer planets are composed of different gasses. These gases are much farther apart in general than the solid planets, just due to the basics of solids and gases. The outer planets usually contain a small core which possesses enough gravitational force to hold the gases around the core.
