The nearest star to us - beyond the Sun, of course - is Proxima, part of the Alpha Centauri triplet. Proxima is a red dwarf star. Looking up at a clear, dark sky, you can see thousands of stars. Yet without binoculars or a telescope, this most common type of star is invisible. The small, cool red dwarfs fill the sky and live practically forever.
