Why is only one side of the moon visible to the US?

One side of the moon always faces Earth because of what’s called synchronous rotation. That is, the moon rotates, or spins on its axis, in the same length of time it takes to orbit Earth. Meanwhile, the opposite side remains hidden from us, so we refer to it as the moon’s far side.
