The moon looks bigger when it’s near the horizon because of how our eyes work. Imagine you're holding a ball close to your face, it looks much bigger than if you hold it far away. The same thing happens with the moon: it's closer to the ground, and things that are near look bigger. When the moon is high up in the sky, there’s nothing around it for comparison, so it seems smaller.
Examples
- The sun looks bigger when it's rising over a mountain than when it's up high in the sky.
- A balloon looks bigger when you hold it near your face compared to holding it far away.
- A car seems bigger in front of a building than when it’s on an empty road.
