BD+06°398 is also known as HR 753, HD 16160, and Gl 105. It is a triple star system comprising of an orange dwarf (A) and two red dwarf (B, C). Star A lies at the minimum mass needed for core fusion of Hydrogen. It's habitable zone would be centered at Mercury-like distances. B lies 1,200 AU away, and is a flare star and a BY Draconis variable star also known as BX Ceti. C is an extremely faint Red Dwarf and only about the size of Jupiter and is separated from A by 24 AU, but likely has extreme eccentricity (0.75). It is near the lower mass limit needed to sustain nuclear fusion. Hubble confirmed its existance in 1995. Mnemonic: BD Ceti.
