Why does the moon look so big sometimes?

When the moon is low on the horizon, it can look unnaturally large in the sky. This is an optical illusion, caused by the moon being close to the horizon. The moon actually looks larger when it is low in the sky because of the way our eyes perceive it. Our eyes are designed to see things in three dimensions, so when we look at an object that is close to us, it appears larger than when we see it in the distance. The moon is actually the same size whether it is high in the sky or low on the horizon, but it can look up to 30% larger when it is close to the horizon.

The moon looks so big sometimes because of an optical illusion called the moon illusion. The moon illusion is an optical illusion that makes the moon appear larger when it is low on the horizon. The moon illusion is caused by the way our eyes perceive the moon. Our eyes are designed to see things in three dimensions, so when we look at an object that is close to us, it appears larger than when we see it in the distance. The moon is actually the same size whether it is high in the sky or low on the horizon, but it can look up to 30% larger when it is close to the horizon. The moon illusion is a well-known optical illusion that has been known since ancient times. The Greek philosopher Aristotle wrote about the moon illusion in 350 BCE. In the 17th century, the moon illusion was explained by the Italian scientist Galileo Galilei. Galileo showed that the moon illusion is an optical illusion by showing that the moon looks the same size when viewed through a telescope.
