How can we classify stars

WebObjects with masses less than about 7.5% of the mass of our Sun (about 0.075 MSun) do not become hot enough for hydrogen fusion to take place. Even before the first such “failed star” was found, this class of objects, with masses intermediate between stars and planets, was given the name brown dwarfs. WebClassification. Scientists can classify stars based on their temperature and color. Stars with low temperatures are typically red, warmer stars are orange or yellow, and extremely hot stars are blue or white. There is a system of classification where a temperatures and color ranges are grouped into classes.
