HD 6114 is a visual binary star system in the northern constellation of Andromeda. With a combined apparent magnitude of 6.46,[1] the star can only be seen with the naked eye by keen-eyed observers even on the best of nights. Based upon an annual parallax shift of Script error: No such module "val".[2] as seen from Earth's orbit, the system is located approximately Script error: No such module "convert". distant.

The binary nature of this system was discovered by O. Struve in 1864. It consists of a magnitude 6.76 primary component with a dimmer magnitude 8.07 secondary. As of 2015 the pair had an angular separation of Script error: No such module "val". along a position angle of 175°.[3] The two stars orbit each other with a period of 450 years with an eccentricity of 0.80.[8]

The primary is an A-type main-sequence star with a stellar classification of A9 V.[5][6] At the estimated age of 863 million years, it is spinning rapidly with a projected rotational velocity of 149 km/s.[10] The star has 1.65[9] times the mass of the Sun and is radiating 21[10] times the Sun's luminosity from its photosphere at an effective temperature of 7,611 K.[9]
