Just hit me now, and maybe I'm way past my bedtime, but I always thought the rotation creates the gravity on planets. But the moon does not spin/turn. So how does the astronauts stay on the moon (if they were ever there)?

I agree, go to bed. But to answer your question- these are 2 different things. Rotation does not create gravity. The mass of an object is what creates gravity. The "heavier" it is, the more gravitational attraction. It doesn't matter if it moves, spins, or flips. It is the mass (what we usually call weight) that creates gravity.
