And that's what formed our moon. Why some planets have many moons is basically because of their size. The planets in our solar system that have more moons are the large planets, Jupiter, Saturn, Uranus and Neptune. They're so big that they can collect a lot of moon. If comets swing by them, they can sometimes absorb comets, they can grab asteroids.
Jupiter is so large that all of the other planets in the solar system are able to fit inside. Its surface gravity is 27 yards squared. This causes objects to weigh more than twice as much as they would weigh on Earth. Jupiter has 62 moons in part due to its high amount of gravity. Its gravity also causes damage to passing asteroids and space matter.
