why does the moon only look huge when it’s low in the sky?
Your eyes are used to things getting smaller in the distance towards the horizon. It's the principle behind perspective in painting/drawing. So a car right next to you is way bigger than a car in the distance, but your brain is used to understanding that they're actually the same size.
The Short Answer
Your eyes are used to things getting smaller in the distance towards the horizon. It's the principle behind perspective in painting/drawing. So a car right next to you is way bigger than a car in the distance, but your brain is used to understanding that they're actually the same size. The moon moves around us and never gets closer or further away as it does so. When it's low in the sky and you can see it alongside distant objects that appear small to you, the illusion comes from your brain thinking "Hey, if it's that big way far away, it must be huge!". Overhead, it's the same size (you can stretch out your arm and use your fingers to see that angularly, it occupies just as much of your vision), but now it's set against overhead clouds, or nothing, and appears smaller.
