Q. Which one of the following planets has largest number of natural satellites or moons? (UPSC Prelims 2009)
Answer: Jupiter
Notes: Jupiter has traditionally been recognized as having the largest number of natural satellites among the planets in our solar system. Although recent data shows Saturn with 146 moons, earlier and many educational sources attribute the highest number to Jupiter with 95 known moons. Mars has only 2 moons, and Venus has none, making Jupiter the correct answer in conventional contexts.
