Some stars are actually bigger than others, and some are closer to us, so appear bigger. The biggest star is UY Scuti, which is 1708 times bigger than the sun. It is 7800 light years away. The closest is Alpha Centauri, at 4.5 light years away.
Note: nearly all stars are so far away that they still appear as just points of light,
even in large telescopes.
The angular size of some stars can be measured using "interferometry".

Why does a medium-siza star appear brighter than the others?
Because some stars are closer then the others. Maybe a star isn't so big, but if its closer then a bigger one, then it looks shinier.
What causes the stars in the sky to appear to be moving?
The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
How is the sun different from other stars relative to earth?
The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
How big are stars to planets?
Planets are a lot bigger than stars except the sun... the sun is a star. So to me the answer is a star is bigger and the stars are also smaller.Let's think about the actual sizes, not just how they appear in the sky.You may be thinking of the apparent sizes as seen from Earth. Stars like our Sun are a lot bigger than planets and there's lots of stars bigger than the Sun.However there are also stars a lot smaller than the Sun. So some stars aresmaller than some planets.For example "white dwarfs" have a lot more mass than the Earth, but they arenot much bigger.Let's be clear though, most stars are bigger than planets.
Why do bigger stars die more quickly?
Bigger stars get hotter, and use up their fuel much faster than smaller stars.
Do the stars reflect light or give out light?
Stars give out light. The sun is a relatively small star but it's a a lot close than the others making it appear bigger. Stars are explosions and give out light.
Why does the moon appear bigger than the stars?
Because it is way closer than other stars!
Why does a medium-siza star appear brighter than the others?
Because some stars are closer then the others. Maybe a star isn't so big, but if its closer then a bigger one, then it looks shinier.
Why does the sun appear bigger and brighter than the other stars?
The sun appears bigger and brighter than other stars because it is much closer to us than any other stars.
Are stars bigger than moons?
Yes, much bigger. The stars appear tiny because they are unimaginably far away. The stars we see at night are suns, some bigger and brighter than out son, some with their own planets orbiting them.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

The apparent motion of stars is due to movement of?
The rotation of the Earth makes the stars appear to move in the sky.

The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
What is the past tense of some stars appear to be brighter than others?
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
Why does the sun appear bigger than the stars?
Because we are closer to the sun than to the stars. The sun is bigger than SOME stars. Stars can be all different sizes. Some stars are in fact smaller than our sun but not as small as they appear to be. On the other hand, some stars are hundreds even thousands times larger than the sun we see. They only look small because they are so far away.
Which is the biggest the sun or a star?
Our Sun is a star, stars are suns. Some stars are bigger than our Sun, others are smaller.
