How about "perfectly aligned with anything relatively at rest to you?" The probability of that is not "near zero", it *is* zero.

Your first hypotheses is correct, including the moons wobble. We *do* observe the moon wobbling from the earth, something like 10 degrees each way. We also pick up a little of the "dark" side of the moon do to the north-south wobble.
