- Apparent distance theory : Apparent distance theory refers to an explanation of the moon illusion that is based on the idea that the horizon moon, which is viewed across the filled space of the terrain, should appear farther away than the zenith moon, which is viewed through the empty space of the sky. This theory states that because the horizon and zenith moons have the same visual angle, the farther appearing horizon moon should appear larger.
