As we are close to so it appears large, while other stars are far away
This video should give you an idea, look from 0:30 onwards
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.
That is one factor. The size of the star is the other.
big
The average star will become a white dwarf at the end of its life.
The average size is about 1500 sqft.
The brightness of a star depends on the star's temperature, size, and distance from Earth.Distance on which you can see the stars.
because it is the nearest star in our planet earth so it will appear as very large hot gases... and the second nearest star is the Proxima Centauri
The sun is a star. It is comparatively large, believed to be in the top 20% for size.
The size of the star, because the smaller the star the hotter it is because of nuclear fusion. So the hotter the brighter.
The surface temperature of the Pollux star is 4,500 K
Our Sun is an average-sized star.
An average star like our own Sun is called a yellow dwarf.
