Because they're so far away. No matter how huge something is, it'll always look that tiny if it's far enough.
Stars appear tiny in the sky because they are extremely far away from Earth, often millions of light years. This great distance makes them appear as small points of light when viewed from our planet. Additionally, the brightness of stars can also make them appear smaller as they overwhelm our vision with intense light.
The Sun isn't especially large, but is still a little larger than average. But the "average" for stars is skewed a bit by the fact that there are so many small stars. We talk about Betelgeuse and Rigel and Sirius, the biggest and brightest stars, but there are far more dwarf stars than giants.

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".
well even though the sun is very small compared to other stars (keep in mind its still atleast 100 times bigger than the earth) its a lot closer by many lightyears than any other star.
No. They are still working on that. There may be LARGE death rays, but no small ones. The power supply needed is still quite large.
The hottest stars still undergoing fusion tend to be blue in colour. These stars rarely get above 50,000 K. Even hotter stars are white dwarfs. They appear white with maybe a blueish tone. They can be as hot as 250,000K.
its hard to know that we still trying to find out
The densest stars are neutron stars; these are "dead stars", in the sense that they ran out of fuel and no longer convert energy. However, they still have a large amount of energy left over from the collapse, which they gradually emit.
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.
no
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.
