Delta Phoenicis, Latinized from δ Phoenicis, is a single, yellow-hued star in the southern constellation of Phoenix. With an apparent visual magnitude of 3.93, it is visible to the naked eye. Based upon an annual parallax shift of 22.95 mas as seen from Earth, it is located 142 light years from the Sun. The star is moving closer to the Sun with a radial velocity of −7 km/s.
This is a G-type giant star with a stellar classification of G8.5 IIIb. It is a red clump star, which means it has reached the stage of its evolution where it is generating energy through helium fusion at its core. It is around 2.3 billion years old with 1.47 times the mass of the Sun. The star is radiating 55 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,790 K.
