Jupiter, the largest planet in our solar system, currently holds the record for having the most moons. Jupiter has a total of 79 known moons. These moons vary in size, shape, and composition. The four largest moons of Jupiter, known as the Galilean moons, are Io, Europa, Ganymede, and Callisto. These moons were discovered by Galileo Galilei in 1610 and are among the most fascinating objects in our solar system.
It's worth noting that new moons are continually being discovered around various planets in our solar system. Therefore, the exact number of moons for any given planet may change as new discoveries are made through ongoing astronomical observations and research.
