This striking phenomenon is known as the moon illusionmoon illusionThe Moon illusion is an optical illusion which causes the Moon to appear larger near the horizon than it does higher up in the sky. It has been known since ancient times and recorded by various cultures.https://en.wikipedia.org › wiki › Moon_illusionMoon illusion – Wikipedia, and the fact that it happens has been well documented since at least the fourth century B.C. Obviously the moon isn’t actually changing size—but the precise reason it seems to be expanding and contracting continues to puzzle scientists today.
it is called waxing. when the lighted part of moon starts growing bigger till it becomes from a new moon to a full moon it is called waxing. What is it called when the moon appears to be growing in the sky from night to night?
This moon illusion might seem like an easy explanation for the sometimes increased size of the moon, but proximity is only part of the equation. According to NASA, scientists don’t actually know why the moon illusion has such a pronounced effect on the way we perceive the moon. By all accounts, it shouldn’t appear nearly as close as it does.
The Moon is always the same size. What we see increasing is the lighted part of the nearside of the Moon. When it is increasing, we call it “waxing”; when we see it decreasing, the word “waning” is used.

What is it called when the moon looks bigger?
The Moon illusion is an optical illusion which causes the Moon to appear larger near the horizon than it does higher up in the sky. It has been known since ancient times and recorded by various cultures. The explanation of this illusion is still debated.
Why is the moon bigger when it rises?
Aristotle believed the Earth’s atmosphere magnifies the moon when it’s near the horizon, causing it to look bigger — but we’ve since learned that he was wrong. The scattering effect of the atmosphere sometimes makes the moon appear orange or red, but it doesn’t alter the moon’s apparent size.
Why does the size of the moon vary?
The moon only changes its apparent size by about 10% throughout a cycle, as evident in this series of photos. This change is due to the moon coming closer to the earth during part of its orbit.
Why does the moon look big sometimes and small sometimes?
This happens because the Moon’s light travels a longer distance through the atmosphere. As it travels a longer path, more of the shorter, bluer wavelengths of light are scattered away, leaving more of the longer, redder wavelengths.
Why does the moon seem to get bigger and smaller?
Al-Haytham suggested that when the moon is overhead, we perceive it to be closer and therefore smaller. But when the moon is rising over a distant horizon, we perceive it to be farther away and therefore larger.
Why does the moon appear bigger tonight?
It is an optical illusion. It only looks bigger near the horizon because it can more easily be compared to familiar objects on the ground. If you hold up a coin in front of your line of sight while looking at the moon and then compare your arm extension for a low moon and a high moon you see that they are the same.
Why does the Moon look bigger in some places?
“When the moon is near the horizon, the ground and horizon make the moon appear relatively close. Because the moon is changing its apparent position in depth while the light stimulus remains constant, the brain’s size-distance mechanism changes its perceived size and makes the moon appear very large.
Where does the Moon look biggest on earth?
All in Your Head But when the moon is rising over a distant horizon, we perceive it to be farther away and therefore larger. One reason why the horizon might appear more distant than the sky overhead is that our brains perceive the shape of “space” as a gently flattened dome rather than a perfectly round sphere.
