Well, not exactly. There are many different types of stars, from the tiny brown dwarfs to the red and blue supergiants. There are even more bizarre kinds of stars, like neutron stars and Wolf-Rayet stars. Letâs take a look at all the different types of stars there are.Red giant Betelgeuse.ed Dwarf Star. Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that theyâre much cooler than stars like our Sun. They have another advantage.
After years of cataloging stars, they were divided into 7 basic classes: O, B, A, F, G, K and M. Note that the spectra classes are also divisions of temperature such that O stars are hot, M stars are cool. Between the classes there were 10 subdivisions numbered 0 to 9. For example, our Sun is a G2 star. Sirius, a hot blue star, is type B3. Why do some stars have strong lines of hydrogen, others strong lines of calcium? The answer was not composition (all stars are 95% hydrogen) but rather surface temperature.
