Because of refraction in the earth's atmosphere: The air density in the earth's atmosphere and therefore also the index of refraction of the earth's atmosphere decrease with increasing altitude. Snellius' law of refraction tells us that light is refracted towards the medium with higher index of refraction. Therefore, the light coming from any star that is not situated directly above the observer takes a curved path bent down towards the observer, arriving at the observer at a steeper angle than had it travelled on a straight line.

Why do stars seem to rotate?
Stars actually do rotate.
What does it means when the moon is next of a star?
It doesn't mean anything. There are always stars next to the Moon. Actually the stars are much farther away, but the stars that happen to be in the same direction seem to be next to the Moon.It doesn't mean anything. There are always stars next to the Moon.

Why do some stars appear smaller than others?
some stars seem smaller than the other because they are further away from earth. many stars are also located in different galaxies and are very bright therefore making it slightly visible.
Why does it seem like stars move across the sky?
Stars appear to move across the sky due to the Earth's rotation on its axis. As the Earth spins, different stars come into view while others disappear below the horizon. This apparent motion is actually the result of the Earth's rotation, not the movement of the stars themselves.
Why do planets seem brighter than stars?
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
Why do some stars look bigger than the other stars?
Some stars appear bigger than others due to their intrinsic luminosity, distance from Earth, and atmospheric effects. Brighter stars or those closer to Earth may appear larger in the sky, while atmospheric distortion can also make stars seem larger than they actually are.
Why are stars pointy?
Stars appear pointy due to atmospheric distortion when viewed from Earth. The Earth's atmosphere causes light from stars to bend and twinkle, making them seem to twinkle and appear pointy. In reality, stars are spherical in shape like our own sun.
Do stars go up in the morning or at in the night?
Stars don't go up at night or in the day because the stars in the universe are always there. You can only see them, however, at night because there is no sunlight to block you from seeing them. The solar energy the stars give off aren't as bright as the sun's, causing them to seem like they aren't there when they actually always are.
Do stars move during the night?
Yes, stars appear to move across the sky at night due to Earth's rotation. This motion is caused by the Earth spinning on its axis, making it seem like the stars are moving when actually it's the Earth moving.
Do stars rotation?
Stars appear to twinkle. The density of air affects how light bends as it passes through the atmosphere. When patches of air of different density come between a star and our eyes, we see different rays of light coming from slightly different parts of the star. The constant movement of air in the atmosphere means stars seem to twinkle.
Why do stars seem to change their colors?
Because their temperature seem to change too
What directions do the stars seem to move as the earth rotates on its axis?
They seem to move to the West, like the Sun does.
