HD 6114
HD 6114 is a visual binary star system in the northern constellation of Andromeda. With a combined apparent magnitude of 6.46, 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 10.4 mas as seen from Earth's orbit, the system is located approximately 108 parsecs (350 ly) 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 1.30″ along a position angle of 175°. The two stars orbit each other with a period of 450 years with an eccentricity of 0.80.
The primary is an A-type main-sequence star with a stellar classification of A9 V. At the estimated age of 863 million years, it is spinning rapidly with a projected rotational velocity of 149 km/s. The star has 1.65 times the mass of the Sun and is radiating 21 times the Sun's luminosity from its photosphere at an effective temperature of 7,611 K.
