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.[2] Based upon an annual parallax shift of 20.9 mas,[1] it is located 156 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.[2]

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 is expanding. 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[7] times the Sun's luminosity from its photosphere at an effective temperature of approximately 7,000.[7]
