Final answer:
Jupiter and Saturn have the most moons due to their large size and strong gravitational pull.
Step-by-step explanation:
The planets with the most moons are Jupiter and Saturn. Jupiter has a total of 79 known moons, while Saturn has 82. The characteristic that these planets share is their large size and strong gravitational pull.
This strong gravitational pull allows them to capture and hold onto numerous smaller objects like moons and asteroids in their orbit. These captured objects become their moons.
For example, Jupiter's largest moons, called the Galilean moons, were most likely captured asteroids or objects from the early solar system.
