How do you classify stars
WebClassify stars based on their properties. Vocabulary. asterism; nuclear fusion reaction; parallax; star; Introduction When you look at the sky on a clear night, you can see dozens, perhaps even hundreds, of tiny points of light. Almost every one of these points of light is a star, a giant ball of glowing gas at a very, very high temperature ...

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.
WebThe Sun is classed as 'G' star, with a temperature of about 5,800 °K. (When talking about the temperature of stars, we usually use the unit 'Kelvin' - 5,800 °K is about 5,500 °C.) The hotter stars are usually much less common than the cooler, redder ones. For example 'O' type stars make up only 1 in every 3 million stars we see.
