Zeta Pavonis
Zeta Pavonis, Latinized from ζ Pavonis, is an orange-hued star in the southern constellation Pavo. Its apparent magnitude is 4.01, which is bright enough to be faintly visible to the naked eye. The annual parallax shift of this star is 14.93 mas as seen from Earth, which provides a distance estimate of approximately away from the Sun. It is moving closer to the Sun with a radial velocity of −16.30. Based upon its motion through space, this star appears to be a member of the Hyades Supercluster.
This is an evolved K-type giant star with a stellar classification of K0 III, which indicates it has exhausted the supply of hydrogen at its core. The measured angular diameter of this star, after correction for limb darkening, is. At the estimated distance of this star, this yields a physical size of about 19 times the radius of the Sun. The star is radiating 155 times the Sun's luminosity.
Zeta Pavonis has a companion, probably optical, of apparent magnitude 12.0 at about 55.6" separation.
