Why does the moon rotation period equal the revolution period. Also most, if not all, other planets moons have the same characteristic, why is that?

Thanks, so is what that's trying to say is that because the earths gravity keeps 1 side of the moon always facing us. Would the moons core being frozen have anything to do with this.

Found this site. I thought it was kinda neat. You punch in how big you want the sun and it calculates the size and distance of all the planets. For example, if the sun was 15 inches, pluto would be .6mm and about a mile away. How could the sun have any affect on something that small that far away.

Well, yeah, but it must have some massive force to do it. Using that 15 inch sun example, if you had a 15 inch magnet that could have an affect on something a mile away, that's some awesome force.

You're scaring me. Gravity and magnetism are extraordinarily different forces. They're so different that even modern science has difficulty hypothesizing their coexistence in one unified theory, but I digress...

electromagnetism is actually a far more powerful force than gravity.

A fifteen inch magnet has more force inward due to magnetism than is does to gravity. So is it only gravity keeping pluto in orbit?
