Question

How do inner planets differ from outer planets?

Answer 1

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.

Explanation:

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
