So basically the answer is simply that that’s the way they all started out.

Some moons, however, do have retrograde orbits. I.e., they orbit in the opposite direction around their respective planets. Some small asteroids and comets also have retrograde orbits due to their small mass being easily affected by larger cosmic objects.

But I bet now you’re all thinking of pizza… 🍕
