Kapteyn's Star is a class M1 red subdwarf about 12.76 light years from Earth in the southern constellation Pictor, and the closest halo star to the Solar System. With a magnitude of nearly 9 it is visible through binoculars or a telescope. Its diameter is 30% of the Sun's, but its luminosity just 1.2% that of the Sun's. It may have once been part of the globular cluster Omega Centauri, itself a likely dwarf galaxy swallowed up by the Milky Way in the distant past. The discovery of two planets—Kapteyn b and Kapteyn c—was announced in 2014.
