"The most common misconception is that it is because you are unconsciously comparing the Moon to foreground objects like trees and houses, or even the horizon itself, and that makes the Moon look bigger than when it is all alone in the sky. This turns out to be false."The explanation I've heard--and the one that seems to make the most sense--is that when the moon is on the horizon, you are viewing it relative to familiar landmarks, like trees, mountains, or buildings, as opposed to seeing it hanging in the sky all by its lonesome
An absolutely brilliant page with some very high level analysis of this illusion.
The Bad Astronomy pages are well worth the pain of perusal generally, some good stuff on science U/Ls.
