Each of these is small and faint, but the B component (individually known as Van Biesbroeck's Star) is one of the smallest and faintest stars known, with less than a tenth of the of the mass of the Sun. The primary star V1428 Aquilae A is known to have at least one planet, a small gas giant following a close orbit around its cool red parent star.
