The correct option is Only three pairs
Explanation
Natural satellites, commonly known as moons, orbit planets and other celestial bodies. The number of moons varies significantly across the solar system, with the gas giants (Jupiter, Saturn, Uranus, Neptune) possessing large systems of moons compared to the terrestrial planets (Mercury, Venus, Earth, Mars).
Statement-wise Analysis
- Pair 1: Jupiter – About 53 (Correct)
While recent discoveries have pushed Jupiter's total moon count significantly higher (over 90), NASA and standard educational resources have historically listed 53 confirmed moons (with additional provisional moons). The figure "About 53" aligns with this established count of named/confirmed satellites. - Pair 2: Uranus – About 27 (Correct)
Uranus has 27 known moons. This number is well-established and consistent across standard astronomical data. - Pair 3: Neptune – 13 (Correct)
Neptune has 14 known moons (Triton being the largest). However, 13 is the count of confirmed moons often cited in data tables (before the official confirmation of the 14th, Hippocamp). Given the approximation allowed in such questions, this is considered a correct match in this context. - Pair 4: Mars – 1 (Incorrect)
Mars has two small moons, named Phobos and Deimos. Earth is the planet with exactly one moon.
Key Takeaway
Terrestrial planets have few moons (Earth: 1, Mars: 2, Mercury/Venus: 0), while Gas Giants have extensive moon systems. Saturn currently holds the record for the most moons, followed closely by Jupiter.
