Question

Quizplus · Accepted Answer

The origin of the various moons around the planets in the solar system is believed to have occurred through all three mechanisms- capturing of asteroids, collision and condensation, and formation from ejected planetary material. Some moons were probably captured asteroids, while others formed through collisions of planetesimals or from material ejected when their planets were struck by large objects. Some moons may have formed through a combination of these mechanisms.
