Krüger 60

A faint binary star in the constellation Cepheus. The two members of the system, magnitudes 10 and 11, orbit each other in a period of 44 years. Since the orbit is seen "face on" and the two stars are easily resolved, the relative motion shows clearly in photographic sequences taken over a period of decades. Both are dwarf M stars and the fainter component is a flare star. At a distance of 13 light years, it is one of the nearest stars to the solar system.
