Which of the following planets is known for having many moons?

Jupiter is known for having many moons, making it the correct answer. It is the largest planet in our solar system and has a diverse and extensive collection of natural satellites. As of now, Jupiter has more than 79 confirmed moons, with the four largest—Io, Europa, Ganymede, and Callisto—known as the Galilean moons, discovered by Galileo in 1610. The presence of these moons is significant for scientific research, as they vary greatly in size, composition, and geological activity, leading to a deeper understanding of planetary formation and evolution.

In contrast, Mercury and Venus are examples of terrestrial planets that do not have any moons, while Earth has just one natural satellite. The stark difference in the number of moons among these planets highlights Jupiter's unique position in the solar system.
