Q1. Which one of the following planets has the largest number of natural satellites or moons?
Explanation
As of 2009, Jupiter had the highest number of known moons (63 at that time). Jupiter’s large number of moons is attributed to its massive size and strong gravitational pull, which allows it to capture a variety of objects into its orbit. However in future years Saturn has since been found to have more moons than Jupiter.
Additional insight:
As of October 2023, Jupiter has 95 confirmed moons, making it the planet with the second-largest number of moons in the solar system. Some of Jupiter’s most famous moons include Ganymede (the largest moon in the solar system), Europa, Io, and Callisto. Saturn has 146 confirmed moons which makes it the planet with the largest number of moons in the solar system. Some of Saturn’s notable moons include Titan (the second-largest moon in the solar system and the only moon with a dense atmosphere), Enceladus, and Rhea.
