So I saw this A New Explanation For the Reddish North Pole of Pluto's Moon Charon and thought Pluto which is smaller than Earth's moon has a moon? which begs the question ... Can a moon have its own moon? Yes, it is possible for a moon to itself have moons and/or rings, and there are a few places where scientists have suggested that this is (or was) the case. However, moons tend to rotate slowly, and this makes it difficult for a moon’s moon to find a stable orbit.
