HD 23596 is a star with an orbiting exoplanet companion in the constellation Perseus. It has an apparent visual magnitude of 7.25,[2] which is too dim to be viewed with the naked eye. Based on parallax measurements, it is located at a distance of 169 light years from the Sun. The system is drifting closer with a radial velocity of −10 km/s.[1]
The stellar classification of this star is F8, making it an F-type star with an undefined luminosity class. It is 20% more massive than the Sun and has 153% of the Sun's girth. The visual luminosity of the star is 2.63 times greater than the Sun, which it is radiating from its photosphere at an effective temperature of 5,953 K. It has an estimated age of five billion years,[3] and is spinning with a projected rotational velocity of 3.6 km/s. The star is considered metal-rich, having a higher surface abundance of iron compared to the Sun.[4]
