      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.
