Which set lists the four outer planets?

• A. Jupiter, Saturn, Uranus, Neptune
• B. Mercury, Venus, Earth, Mars
• C. Earth, Mars, Jupiter, Saturn
• D. The four outer planets: Jupiter, Saturn, Uranus, Neptune

Answer: (D)

Think about which planets lie beyond the asteroid belt and are classified as the outer or Jovian planets. The outer planets are Jupiter, Saturn, Uranus, and Neptune. The set that lists these four names is exactly identifying all four outer planets and no others, which is why it’s the correct choice. The other options mix in inner, rocky planets like Mercury, Venus, Earth, and Mars, so they don’t represent the four outer planets. Remember, the four inner planets are the ones closer to the Sun and smaller in size, while the outer planets are the larger gas giants beyond them.
