Motion parallax is the phenomenon where objects closer to the observer appear to move faster than objects further away, even though the observer is moving at a constant speed. This is why the moon, which is so far away, seems to "follow" you as you move; the relative motion of closer objects provides a contrast that makes the moon's position seem constant relative to the observer.
