It depends on the size, distance, and luminosity of a star. Our Sun looks quite big in the sky compared to other stars but only because it is so much closer. It is actually quite small compared to others but they are a much greater distance away. And lastly, dim stars can be close to Earth but don't appear very big or bright because they don't give off much light.
What else can I help you with?
What makes some stars appear brighter than others the temperature or the size?
It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.
Suppose the angular separation of two stars is samller than the angular resolution of your eyes How will the stars appear to your eyes?
If the angular separation of two stars is smaller than the angular resolution of your eyes, they will appear as a single point of light rather than two distinct stars. This is due to the limit of your eyes' ability to resolve fine details at such a close angular distance.
Why do stars appear yellow?
Stars appear yellow because of their surface temperature. When a star is at a medium temperature, it emits a mix of colors that our eyes perceive as yellow. Stars cooler than the Sun appear more red, while hotter stars appear more blue.
What does it mean when a star reaches the stage where its light becomes white?
When a star's light appears white, it means the star has reached its mature phase known as the white dwarf stage. This occurs when the star has exhausted its nuclear fuel and has collapsed to a smaller, denser state. White dwarfs emit a combination of different light wavelengths that appear white to our eyes.
A bright star can appear dimmer than a less bright star if the bright star is?
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
Why does a star appear to be smaller the sky than it is?
Stars appear very small because they are very far away.

When was Star Eyes created?
Star Eyes was created in 1960.
Where is Leia in LEGO's Indiana Jones sets?
Leia is a Star Wars character and wouldn't appear in the Indiana Jones set. She does appear in some Star Wars sets, however.
Star which do not change its position in the night sky?
The only star that does not appear to move in the Sky is Polaris, the North Star. (Actually it does move in a TINY circle, but the apparent motion is too small to notice.)
Why do stars appear yellow?
Stars appear yellow because of their surface temperature. When a star is at a medium temperature, it emits a mix of colors that our eyes perceive as yellow. Stars cooler than the Sun appear more red, while hotter stars appear more blue.
Morning star and evening star are the same?
Not necessarily. Though some appear as morning and evening 'stars'. Venus for example.
Why can some stars been seen first than after a while more star are seen?
Your eyes adapt to the darkness. Also, some stars are so small to the human eye from Earth that it takes a few seconds to spot them.
Why do stars seem to twinkle when viewed by naked eyes?
Stars twinkle because of turbulence in Earth's atmosphere. As light from a star passes through the atmosphere, it gets distorted by varying air temperatures and densities. This causes the star's light to appear to flicker or twinkle when viewed from the ground.
Which one of the star is hottest?
If you mean "What is the hottest star". The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. So the hottest stars in the Universe are going to be a blue star, and we know they're going to be massive.
What Star Wars Movie did yoda not appear?
Yoda did not appear in the original Star Wars, A New Hope.
