Looks of the star
Why are stars so bright? Stars are very hot. The sun is not the brightest star. The sun is just closest to us thats why it seems so big. The reason we cant see the other stars durning the day is because the sun is so bright. The stars are different colors because when they form through atoms there is diffrent tempature . The hotter it is it will have a buler color. If you have ever seen a match it is blue at the bottom and orange at the top. The stars are diffrent colors depending on there temapture.
