There isn’t a single answer to this question since there are many different reasons why a planet might have multiple moons or no moons at all.

One reason a planet might have multiple moons is if it was formed from the collision of two or more smaller objects. When these objects collide, they can break apart and form into multiple smaller pieces. Over time, these smaller pieces can coalesce and form into multiple moons orbiting the planet.

Another reason a planet might not have any moons is if it is simply too small to hold onto one. A moon requires a certain amount of gravity in order to orbit a planet and remain in place. If a planet is too small, it might not have enough gravity to keep a moon in orbit.There isn’t a single answer to this question since there are many different reasons why a planet might have multiple moons or no moons at all.One reason a planet might have multiple moons is if it was formed from the collision of two or more smaller objects.
