Hi, this may be a completely stupid question, but in my world there are two moons, one silver, one red. I would like them to rotate in opposite directions if possible, but I am not sure if this is physically possible. I know it shouldn't matter seeing as it's my world but I do like to be correct if I can.
So I guess I have 2 questions, is this possible and if so, can someone give me a quick, SIMPLE explanation of how it would work.
Yes, they can. At least at first. If you have one moon who originated from the world itself, and the second which got caught in world's gravity well, then it is possible for them to orbit in opposite directions. Problem is that such a setup may not be very stable, which might then result in one or both moons crashing on the planet or flying away after some time.
