Which planet has the largest number of natural satellites or moons?

The moon is a celestial body that revolves around a planet or small planet (or sometimes another small Solar System body). 

Jupiter has more than 80 moons which makes it the planet with the most moons in our solar system. These moons vary in size and characteristics, with the four largest moons, known as the Galilean moons, being Io, Europa, Ganymede, and Callisto.

Hence, the correct option is "Jupiter".
