∙ 14y agoYes there are.
Stars can vary in size from the size of a city (Neutron star), through the size of the Earth (White dwarf) to our own Sun which is 100 times larger than the Earth right up to the largest know star VY Canis Majoris, which is about 2,100 time larger than our own Sun.

∙ 11y agoObviously stars are all made from matter...so this question could be addressed as; how do forming stars obtain more matter. The answer is simply more gravity. Gravity is defined as the attraction force between two masses. So as the star attracts more matter its gravity increases and this process of attracting matter speeds up. But the only way gravity can increase is if there is plenty of matter available. Matter isn't spread out uniformly across the universe often its clustered in vast 'pockets' of gasses and particles called 'Nebula's', these are where stars are born. If a star is forming inside a particular large nebular it has more matter available therefore the stars gravity can continue to grow and create a larger star than a star in a nebular with less matter. This isn't the only reason how star size varies but is the easiest to explain. Its also easier to understand as our sun was created inside the same nebular as other local stars which is why we don't find particularly larger stars close to earth; which is probably a good thing.

∙ 12y agoDepending on the classification of a star to include stellar remnants. Sizes are approximate and are for comparison purposes only .
- Black hole = 0.
- Neutron Star = A city
- White Dwarf = The Earth
- Black Dwarf = The Earth
- Brown Dwarf = About the same size as Jupiter.
- Red Dwarf = About 2 times the size of the Earth up to 1/2 the Sun
- Yellow Dwarf = Our Sun
- Blue giant = Twice the size of the Sun
- Red Giant = Ten to a hundred times larger than our Sun
- Red Supergiant = 200 to 800 times larger than our Sun
- Red Hypergiant = Greater than 800 times larger than our Sun.

∙ 11y agoIt is easy to explain. When a star forms from a gas cloud, or nebula, it accretes mass. Depending on how much mass the star gets from the cloud, it will be of different sizes. The large stars burn faster and hotter because they need to produce more heat and other radiation pushing outward to resist the tremendous force of gravity trying to collapse them. You should look up the H-R diagram. It puts stars in categories based on their spectral types (colors) and masses. Large blue giants like Rigel in Orion are very hot and have relatively short life spans, while medium, stable stars like our sun fall into the middle section of the visible spectrum. They are yellow, and burn steadily for at least 10 billion years. Smaller stars are red dwarfs, and they burn cool and for thousands of billions of years.
Remember the ROY G BIV visible spectrum. Red light has the least energy and the longest wavelengths, which is why cooler stars are red. Blue light has the most energy and the shortest wavelengths, which is why the hottest stars are blue/white.
The mass a star gets when it forms determines its color and its size and also how long it will burn before it goes nova or supernova, depending on the mass.

∙ 13y agoThey are big and hot, but they are also very, very far away from us.

Why do some stars look bigger than the other stars?
This is either because the star in question is actually bigger than other stars, or became it is closer to the observer (Earth) than other stars.
Why do some stars look brighter than others?
Some stars make more nuclear fusion, or just have more energy.
How come some stars look brighter that others?
that's because some stars are closer to the earth; another reason is that some stars get more sunlight than others; another reason IS that the star might not have that much enregy
Is the sun bigger or smaller than other stars?
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
Is your sun smaller or bigger than stars in the night sky?
some stars are smaller than sun remaining stars are bigger than sun.
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.
Why do some stars look bigger than the other stars?
This is either because the star in question is actually bigger than other stars, or became it is closer to the observer (Earth) than other stars.
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.
Why do some stars look brighter than others?
Some stars make more nuclear fusion, or just have more energy.
How come some stars look brighter that others?
that's because some stars are closer to the earth; another reason is that some stars get more sunlight than others; another reason IS that the star might not have that much enregy
What makes some stars appear bigger than others?
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".
Are large stars bigger or is the sun bigger?
Some stars are larger than the sun.
Is the sun bigger or smaller than other stars?
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
Can stars have different colors?
Stars do have different colours. If you look carefully, you will see that there are differences between the colours of stars. Some are very different in colour to others, but you will only notice if you look at them carefully.
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.
How much bigger is the sun than other stars and why is it more important?
The sun is bigger than some stars but smaller than others. It is more important to us than other stars because it is the only one close enough to provides us with a substantial amount of energy.
Is your sun smaller or bigger than stars in the night sky?
some stars are smaller than sun remaining stars are bigger than sun.
