The outer planets are gas planets
Inner planets are mostly rock and outer planets are mostly gas.

the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
The outer planets, also known as the gas giants, are located beyond the asteroid belt in our solar system. They include Jupiter, Saturn, Uranus, and Neptune. They are significantly larger than the inner rocky planets and consist mostly of gases and liquids.
The main factor that separates the inner rocky planets from the outer gas planets is their composition and distance from the Sun. The inner rocky planets, including Mercury, Venus, Earth, and Mars, are closer to the Sun and have solid surfaces made primarily of rock and metal. The outer gas planets, like Jupiter, Saturn, Uranus, and Neptune, are located farther from the Sun and are composed mostly of gases and liquids, with no solid surface.
The main difference is that the inner planets are smaller and are nearer the sun te outer planets are after the earth starting with Mars and ending with Pluto.
Jupiter is an outer planet, also called a Gas Giant. The Main Asteroid Belt divides the inner planets from the outer planets.
Outer planets are made up of gas and dust particles, and are farther out due to their gravitational attraction to the sun, while inner planets tend to be rocky and smaller.
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
