Why the Moon looks bigger near the horizon?

When it's full moon creates an optical illusion that confuses observers since Aristotle. Rising of the moon, especially full, look strangely huge near the horizon and seem to be less and less, when you get up in the night sky.

Moon illusion exists only in your head. The moon does not change size, and although the distance to Earth varies a little with time, it is too slow, for one night, there was a significant transformation.

If you want proof that the moon illusion — a completely psychological phenomenon, just measure the moon near the horizon and high in the sky with a ruler. The "lower" the Moon will appear much larger, but a ruler will show that its diameter is not changed.

The cameras also help to bring the moon to clean water. Do consistently a few photos of the moon from the same point, and then combine them — it is obvious that the size of the satellite has not changed.
