- Nope. Sorry. It's just an illusion. When the moon is on the horizon,
- your brain puts it in relation to the things that are in the line of sight,
- like trees and buildings and it looks big against them. When the moon is
- overhead, there are no such things and it "looks" smaller. The actual size
- of the moon that you see does not change. That's why it is called an illusion.
