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, having consumed the hydrogen at its core and tracked away from the main sequence. It has 2.33 times the mass of the Sun and has expanded to about 11 times the Sun's radius. The star is radiating 81.3 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,948 K.
