Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → D, C, B, A
The giant outer planets hold dozens of moons each, while the small rocky planets have few or none.
D. Saturn — has the most moons of any planet: 274 confirmed by 2025, most of them small bodies a few kilometres across.
C. Jupiter — comes second with more than 90 known moons, among them the four large Galilean moons.
B. Uranus — has fewer than 30 known moons.
A. Mars — has only two small moons, Phobos and Deimos.
Tip: Older books put Jupiter first. The lead has changed hands as new moons were confirmed; Saturn has been ahead since 2023, when dozens of its newly found moons were added.
