HD 11506 is a star in the equatorial constellation of Cetus. It has a yellow hue and can be viewed with a small telescope but is too faint to be visible to the naked eye, having an apparent visual magnitude of 7.51.[2] The distance to this object is 167 light years based on parallax, but it is drifting closer to the Sun with a radial velocity of −7.5 km/s.[1] It has an absolute magnitude of 3.94.[2]
This object is an ordinary G-type main-sequence star with a stellar classification of G0V,[3] which indicates it is generating energy via hydrogen fusion at its core. It is around 1.6[4] billion years old and is spinning with a projected rotational velocity of 5 km/s.[6] The star has 112% of the mass of the Sun and 106% of the Sun's radius. The spectrum shows a higher than solar abundance of elements other than hydrogen and helium – what astronomers term the metallicity.[5] The star is radiating 117% of the Sun's luminosity from its photosphere at an effective temperature of 5,833 K.[4]
