Stein 2051 (Gliese 169.1, G 175-034, LHS 26/27) is a nearby binary star system, containing a red dwarf (component A) and a degenerate star (white dwarf) (component B), located in constellation Camelopardalis at 18.1 ly from Earth. The brighter of this two stars is A (red dwarf), but the more massive is component B (white dwarf). Stein 2051 is the nearest system of Red Dwarf and White Dwarf type.[note 1]
^40 Eridani BC is also a system composed of a red dwarf and white dwarf (component B is a white dwarf, and component C is a red dwarf), and located closer (at 16.25 light-years), however, it is not a separate star system, but a subsystem of the 40 Eridani triple star system.
In left column are stellar classes of primary members of star systems. Bold are systems containing at least one component with absolute magnitude of +8.5 or brighter. Italic are systems without known trigonometric parallax.
