* Distance: The moon is much, much closer to Earth than any star. It's our celestial neighbor, while stars are light-years away.
* Size: While the moon is relatively small compared to the sun and even other planets, it's still massive compared to the stars we see.
* Perspective: Our brains interpret size based on our understanding of distance. Since the moon is so close, we perceive it as larger.
Think about it this way: a car a few meters away looks bigger than a skyscraper miles in the distance, even though the skyscraper is actually much larger.
Here's a fun fact: the moon's apparent size can actually vary slightly depending on its position in its orbit around Earth. This is why we sometimes see the moon appear larger at certain times than others.
