Why do the stars seem to be slightly higher than they actually are?

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.
What causes constalations?
constellations are just pictures that the stars seem to be arranged in from our viewpoint on Earth. Because of this, constellation aren't actually objects, they're just what we see. What we see as constellations are individual stars that seem to form a picture (But probably aren't very close to each other.
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 does it seem like stars move across the sky?
because the worl is spinning slowly and because the clouds move and make it seem like stars are moving.
Why do stars rotate?
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.

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.
Why do stars seem to make a circle in the sky?
The stars, as seen from the Northern Hemisphere, appear to circle around Polaris, the North star. They seem to circle around the north pole because the Earth rotates, while the stars are still. As we spin around, stars move out of our view and new ones enter. When looking up to the North pole, it is possible to see stars appear to be slowly spinning around the North star. In the Southern Hemisphere there is no conveniently located star but the stars still seem to spin around a point in the sky. The Sun seems to circle the Earth but again, the Earth is rotating and the sun is still. It's actually Earth that is spinning.
How many stars are double or triple stars?
Current observations seem to suggest that about 50% of all stars are multiple star systems
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.
