Zeta Pavonis, Latinized from ζ Pavonis, is an orange-hued star in the southern constellation Pavo. Its apparent magnitude is 4.01, [2] 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, [1] which provides a distance estimate of approximately 420 light-years (130 parsecs) away from the Sun. It is moving closer to the Sun with a radial velocity of −16.30. [4] Based upon its motion through space, this star appears to be a member of the Hyades Supercluster. [7]
This is an evolved K-type giant star with a stellar classification of K0 III, [2] 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 2.63±0.07 mas. [8] At the estimated distance of this star, this yields a physical size of about 19 times the radius of the Sun. [5] The star is radiating 155 [2] times the Sun's luminosity.
Zeta Pavonis has a companion, probably optical, of apparent magnitude 12.0 at about 55.6" separation. [9] [10]
