Inner planets tend to be smaller, are solid, and have few moons whereas outer planets are typically larger, made of gas, and have multiple moons and rings around them.

The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Jupiter, Saturn, Uranus, and Neptune. (Pluto is no longer considered a planet.)

Inner planets:
1. Smaller than the outer planets
2. Solid (and therefore dense)
3. Few moons
4. No rings

Outer planets:
1. Larger
2. Made up of gas (and therefore less dense than inner planets)
3. Multiple moons compared to the inner planets
4. Rings encircling them
