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".
What else can I help you with?
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.
Why does a medium-siza star appear brighter than the others?
A medium-sized star may appear brighter than other stars due to its luminosity, which is a measure of the total amount of energy it emits per unit time. This brightness is determined by factors such as the star's size, temperature, and distance from Earth. In general, larger and hotter stars tend to be more luminous and thus appear brighter in the night sky.
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.
Why does the moon appear bigger than the stars?
Because it is way closer than other 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 does the moon seem bigger than any other star?
The moon is much closer to Earth than any other star, which makes it appear larger in the sky. Stars are actually much larger than the moon, but their distance from Earth makes them appear as tiny points of light in the night sky.
Why does the sun look bigger than stars?
The sun looks bigger than stars because it is much closer to Earth compared to the stars. Stars are actually much larger than the sun, but their distance makes them appear smaller in the sky. The sun's brightness and proximity to Earth make it appear larger and more dominant.
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.
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 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.
Why does some stars appear dimmer than others?
Stars appear dimmer than others due to factors such as distance from Earth, size, age, and intrinsic brightness. Stars that are farther away will appear dimmer, as less light reaches us. Similarly, smaller or older stars may be dimmer because they produce less light compared to younger, larger stars.
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.
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.
