M dwarfs are the most common
Bright stars are rare, dim stars are common, so class M are the most common that we can see, but even dimmer ones are postulated to be even more common.
Type-O are the hottest but there are very few. Then type-B, there are more of them but still not a lot. Then you have type-A, which are very common, then F, then G like the Sun, then K and then the coolest common ones, type M which are the red stars like Betelgeuse.
M class stars are the most common and account for around 76.5% of all stars that are on main sequence.. They are normally red dwarfs, but can include red giants and red super-giants like Betelgeuse and Antares.
Stars are classified according to temperature, with type O stars being the hottest, then B, A, F, G, K, M. The Sun is a type G star.
The stars with an A-type spectrum are the hottest common stars, but early-stage stars with a B-type spectrum are even hotter. The order of temperature is B-A-F-G-K-M for common stars. The M-type stars are the coolest common stars and they definitely look red, e.g. Antares, Betelgeuse. Remember the order by learning this: Be A Fine Girl, Kiss Me!

Correct. M-type stars on the main sequence are called red dwarfs.
Type-O are the hottest but there are very few. Then type-B, there are more of them but still not a lot. Then you have type-A, which are very common, then F, then G like the Sun, then K and then the coolest common ones, type M which are the red stars like Betelgeuse.
If a star has oxygen, then it is classified as an M-star. The chemistry of M-stars is relatively simple with water as the most important source of molecular opacity. However, transition metal oxides, particularly TiO, are also found to have prominent spectra.

They are yellow and red stars. When the light from stars started to be analysed with spectroscopes, all the stars were classified into different types of spectrum. The main spectral types are A, F, G, K and M, with A the hottest and M the least hot. A-type stars are white (Rigel), while M types are red (Betelgeuse). The Sun is a G type of very average temperature.
Brown is the most common color.
