The seven main types are M, K, G, F, A, B and O. M stars are the coldest stars and O stars are the hottest. The full system contains other types that are hard to find: W, R, N, and S. The closest star to the Earth, the sun, is a class G star.

What are the color of the stars from hottest to coolest?

The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red. A color index of a star is the difference in the magnitudes measured at any two wavelengths and is one way that astronomers measure and express the temperature of stars.

What is the correct order of star colors?

What color are main sequence stars? Temperature translates to color, and this relationship between color and brightness (luminosity) for hydrogen-burning stars is called the main sequence. Massive hydrogen-burning stars are blue-white, the Sun is yellow, and low-mass stars are orange and red.

What is the correct order of star colors from hottest to coolest quizlet?

(Notice that temperature is related to color, and follows the order of the colors in the rainbow: Blue (or violet) stars are the hottest, while red stars are the coolest.)
