Comparing and Contrasting Inner and Outer Planets!

There are two different groups in the solar system, the inner planets and the outer planets. the all orbit the same sun, are named after Roman mythology, and have all been explored by a spaceship/rocket. The inner planets are Mercury, Venus, Earth, and Mars. They are close to the sun and are on the inside of the asteroid belt. The inner planets are also called the terrestrial planets because they have a solid surface and are made of iron and nickel and other heavy metal. These planets have little or no moons. The outer planets are Jupiter, Saturn, Uranus, and Neptune. They are far from the sun and are on the outside of the asteroid belt. The outer planets are called the gas giants or the Jovian planets, they are called this because they are composed of gas and have a liquid core. All of the outer planets have rings (even if they are not very noticeable) and many many moons.

The project where we searched up all of the patterns and relationships between the planets helped me understand this concept well.
