Zeta Pavonis, Latinized from ζ Pavonis, is an orange-hued star in the southern constellation Pavo. Its apparent magnitude is 4.01,[1] 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,[2] which provides a distance estimate of approximately Template:Convert away from the Sun. It is moving closer to the Sun with a radial velocity of −16.30.[3] Based upon its motion through space, this star appears to be a member of the Hyades Supercluster.[4]
This is an evolved K-type giant star with a stellar classification of K0 III,[1] 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 Template:Val.[5] At the estimated distance of this star, this yields a physical size of about 19 times the radius of the Sun.[6] The star is radiating 155[1] times the Sun's luminosity.
Zeta Pavonis has a companion, probably optical, of apparent magnitude 12.0 at about 55.6" separation.[7][8]
