HD 24160 is a single[9] star in the equatorial constellation of Eridanus. It has the Bayer designation g Eridani. It is visible to the naked eye with an apparent visual magnitude of 4.17.[2] The distance to HD 24160 can be estimated from its annual parallax shift of 14.98 mas,[1] yielding a separation of 218 light years. It is moving further from the Earth with a heliocentric radial velocity of +2 km/s.[4] This object is a coronal member of the Ursa Major Moving Group of stars that share a common motion through space.[10]

At the age of 1.76 billion years old, HD 24160 is an evolved G-type giant star with a stellar classification of G7 III,[3] having consumed the hydrogen at its core and tracked away from the main sequence. It has 2.33[5] times the mass of the Sun and has expanded to about 11[6] times the Sun's radius. The star is radiating 81.3[5] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,948 K.[5]
