Proxima Centauri is a red dwarf in the Alpha Centauri system. It's so dim that you can't see it with the naked eye-you need a telescope, and you also need to be in the Southern Hemisphere. In fact, of all the stars and brown dwarfs that are within 16.3 light-years of our solar system, only 12% of them can be seen without the aid of technology.
