HD 14622

HD 14622 is a single^[6][10] star in the northern constellation of Andromeda. It is dimly visible to the naked eye under good seeing conditions, having an apparent visual magnitude of 5.81.^[1] Based upon an annual parallax shift of 20.7 mas,^[2] it is located 158 light years away. The star is moving closer to the Earth with a heliocentric radial velocity of −35 km/s,^[5] and is predicted to come within 96 light-years in around 812,000 years.^[1]

The stellar classification of HD 14622 is F0 III–IV,^[3] showing a mixed spectrum of an evolving subgiant and giant star; suggesting this is an intermediate-mass star that has used up its core hydrogen and evolved away from the main sequence. However, evolutionary models show it is still on the main sequence.^[2] The star is suspected of being slightly variable, but this has not been conclusively proven.^[4] It is around 890^[6] million years old with 1.69^[6] times the mass of the Sun. The star is radiating 8.4 times the Sun's luminosity from its photosphere at an effective temperature of approximately 7,241.^[7]
