“Wow the moon looks huge tonight!” We’ve all said it, but is the moon ever larger or closer at the horizon? (No, it’s not.) Is it some visual magnification by the atmosphere? (Nope, evidently that’s not why either.)

The answer(?): evidently our brains are playing tricks on us when we see a huge moon. The perception of the moon’s size is influenced by what’s surrounding it. (Or is it?)

Created by Mitchell Moffit and Gregory Brown, this ASAP Science video, The Moon Illusion explains why the moon looks larger near the horizon. There’s also more information here and here.
