Gliese 105 (also known as 268 G. Ceti) is a triple star system in the constellation of Cetus. It is located relatively near the Sun at an estimated distance of less than 24 light years,^[1] but even the brightest component is barely visible with the unaided eye (see Bortle scale). No planets have yet been detected around any of the stars in this system.

The companion star B has a common proper motion with A, and the two have an estimated separation of 1,200 AUs. It is a BY Draconis variable star that has been given the designation BX Ceti.

The third companion C lies much closer to A, presently at a distance of approximately 24 AU. The pair A-C have an estimated orbital period of 61 years. C's orbit is estimated to have a high eccentricity of around 0.75 and a semi-major axis of 15 AU,^[9] giving an aphelion of 26.25 AU and a perihelion of just 3.75 AU. Component C is a relatively minuscule star that lies at the low end of the mass range needed to achieve nuclear fusion.

From the surface of a theoretical Earth-like planet at 0.55 AU distance from Gliese 105 A, near the inner edge of that star's habitable zone, component C at perihelion would only ever get about half as bright as the full moon does, despite it being a star, and at aphelion it would appear about as bright as Venus becoming barely even visible to the naked eye in the daytime.
