Moon illusion is a psychological effect that makes the Moon appear larger when it is close to the horizon, although its actual size remains the same.
Several theories have been proposed to account for this perceptual illusion:
- One contributing factor could be related to how our brains perceive the size of objects based on their distance from us.
- Another aspect of the Moon illusion may involve our brain’s expectations regarding the distance of objects near the horizon.
- Objects in the lunar view may contribute to the illusion by providing depth cues that trick our brains into perceiving the Moon as both closer and larger than it is.
