Yes. There are actually a few ways to distinguish them.
****************************************************************************************
One is by their mass.
In this case, we usually talk about low, intermediate and high-mass stars. The Sun would be a low-mass star.
****************************************************************************************
Another is by colour.
Stars that are blue are hotter, and stars that are red are cooler. So this gives away their temperature at their surface.
****************************************************************************************
Yet another, is whether the star has a companion or not.
We think most stars do, and we call them binary stars as there are two of them. Some might be even more, like 3 stars together. But some may be single, like the Sun seems to have no companion star.
Yes, we classify starts in seven different types “O,B,A,F,G,K,M” O starts are the hottest and they are normally blue, G starts are yellow stars like our sun and M stars are the coolest . You can learn this with the phrase “Oh Be A Fine Guirl Kiss Me”
