Which of the following planets is not classified as a terrestrial planet?

• A. Earth
• B. Mars
• C. Venus
• D. Jupiter

Answer: (D)

Jupiter is not classified as a terrestrial planet because it is a gas giant, which is fundamentally different in composition and structure from terrestrial planets. Terrestrial planets, such as Earth, Mars, and Venus, are characterized by their solid, rocky surfaces, and they typically have a higher density and smaller size compared to gas giants. Jupiter, on the other hand, is composed mainly of hydrogen and helium and lacks a solid surface. Its immense size and gaseous atmosphere set it apart from the terrestrial planets, making it part of a different category in the solar system.
