The sun is a typically star, with a visible surface called a photosphere, which an atmosphere …

…of these classes are all similar chemicals composed and arranged in temperature order from hottest to coolest. The absolute surface temperature of the various star groups are as followed: O- 22,200c B-13900c A-10000c F-6650c G-5540c K-3870c M-1760c All go from hottest too coolest. The interior temperature of the average star is about 20,000,000c. Scientists have found a lot out about stars and we even have more to figure out.
