Which of the following is an outer planet of the solar system?
- A.Venus
- B.Earth
- C.Mercury
- D.Saturn
Correct answer
Explanation
The correct answer is D, Saturn. Saturn lies beyond the asteroid belt, so it is an outer planet. The eight planets are divided by the asteroid belt that runs between Mars and Jupiter. The four inner planets, Mercury, Venus, Earth and Mars, are small, rocky and dense, with solid crusts and few or no moons; they are called terrestrial planets. The four outer planets, Jupiter, Saturn, Uranus and Neptune, are huge balls of hydrogen and helium with low density, ring systems and many moons; they are called Jovian or gas giant planets. Saturn is the second largest planet and its bright rings make it the easiest to recognise. Option A is wrong because Venus is the second planet from the Sun and an inner planet. Option B is wrong because Earth is the third planet and also an inner one. Option C is wrong because Mercury is the smallest planet and the closest to the Sun. Exam tip: four rocky planets inside the asteroid belt, four gas giants outside it.
