Planets in our solar system have been classified as either inner or outer planets because of their characteristics. Explain the difference between the inner and outer planets in our solar system.

• The inner planets are farther away from the sun and therefore, receive less sunlight. The inner planets are also larger in size than the outer planets and have only one moon.

• The inner planets are closer to the Sun and therefore, receive more sunlight. The inner planets are also smaller in size than the outer planets and have fewer moons.

• The inner planets are closer to the Sun and therefore, receive more sunlight. The inner planets are all the same and the outer planets are all different sizes.

• The inner planets are farther away from the Sun and therefore, receive more sunlight. The inner planets are also smaller in size than the outer planets and have fewer moons.
