HIP 14810 is a star with three exoplanetary companions in the northern constellation of Aries. It positioned about 1.3° to the north of Delta Arietis,[7] but is too faint to be visible to the naked eye with an apparent visual magnitude of 8.6.[2] The system is located at a distance of 165 light-years from the Sun based on parallax measurements,[1] but is drifting closer with a radial velocity of −5 km/s.[2]
This is an ordinary G-type main-sequence star with a stellar classification of G6V.[2] It has a relatively low activity level and a low projected rotational velocity of 0.5 km/s, which indicates it is an old star with an age of around eight billion years.[5] The star has a high metallicity with a mass and luminosity about the same as the Sun.[4]
