HR 753 (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 too faint to see directly with the unaided eye. 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, at a distance of approximately 24 AU. The pair A-C have an estimated orbital period of 61 years. Component C is a relatively minuscule star that lies at the low end of the mass range needed to achieve nuclear fusion.
