![]() What Makes a Star?![]() ColorsWe have a yellow star. That's the Sun. Some systems have red stars. Others have a blue tint. The color of a star depends on its surface temperature. Bluer stars have a higher surface temperature. Lower temperature stars give off a lot of red light.The Three BasicsAstronomers look at three main characteristics of stars. They study luminosity (brightness), temperature, and radius (size). Each of these three factors can tell you a lot about a star. Take our star for example, the Sun. As far as stars are concerned, it is rather small. The yellow color tells you it has a nice, medium temperature. The small radius also gives an indication that it not much of a powerhouse. Last is the luminosity. On Earth, the Sun may seem bright. Compared to other stars it is only a candle. Astronomers consider our Sun to be in the main sequence of its development.![]() ![]() |
