Which term best describes the four planets farthest from the Sun?

• A. Moon groups
• B. Dwarf planets
• C. Inner planets
• D. Outer planets

Answer: (D)

Planets are talked about by where they sit relative to the Sun. The four closest to the Sun are the inner planets, and the four farthest away are the outer planets. This term fits perfectly because it describes their position in the solar system, beyond the asteroid belt. The other phrases don’t describe location in the same way: moon groups aren’t a planetary category, dwarf planets are smaller bodies, and inner planets refer to the closer ones, not the farthest. So the best term for the four planets farthest from the Sun is outer planets.
