Why did the moon look so big?
It was probably 9:30 and it was dark, and the moon was a crescent, and it was big and yellow-ish-orange. But it wasn't right on the horizon, and it wasn't way up in the sky. Why was it so big? Is it normal?

Most agree that the illusion is a matter of perception--a trick of the brain. Some argue that the horizon Moon looks bigger because it is framed by smaller objects like trees, houses and hills, making it huge by comparison. However, that doesn't explain why the moon looks so big rising over the flat expanse of the ocean.
Several complicated theories involving the brain's visual system also try to explain the moon paradox. Here's a simplified version of one popular explanation: The brain perceives the sky (and Moon) above us as closer than the sky (and Moon) at the horizon. When an object is perceived to be nearer, the brain may compensate by making it look smaller to us. Likewise, an object thought to be farther away will be seen as larger.
