Why does the moon look so much bigger when it's on the horizon?

The moon looks bigger on the horizon because it’s next to things we know are small, like trees and buildings, making it seem larger.

When the moon is near the ground, it's right beside things you see every day. Think of it like a big balloon floating next to your toy car, the car looks tiny compared to the balloon, so the balloon feels bigger. That’s how the moon feels when it's on the horizon.

When the moon is high in the sky, there are no trees or buildings nearby to compare with it. It's like looking at that same big balloon up in the air, now it has nothing to compare with, so it doesn’t feel as big anymore.

The size of the moon doesn’t actually change, it’s just our eyes playing a little trick on us!
