Zeta Apodis
Zeta Apodis, Latinized from ζ Apodis, is the Bayer designation for a star in the southern constellation of Apus. It has an apparent visual magnitude of +4.78, which is bright enough to allow it to be seen with the naked eye. The distance to this star is known from parallax measurements to be around.
The spectrum of Zeta Apodis matches a stellar classification of K2 III, with the luminosity class of III indicating it is an evolved giant star. The measured angular diameter of this star, after correction for limb darkening, is. At the estimated distance of Eta Draconis, this yields a physical size of about 11 times the radius of the Sun. The outer atmosphere has an effective temperature of 4,388 K, which gives it the orange-hued glow of a K-type star.Naming
In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, 異雀, meaning Exotic Bird, refers to an asterism consisting of ζ Apodis, ι Apodis, β Apodis, γ Apodis, δ Octantis, δ1 Apodis, η Apodis, α Apodis and ε Apodis.
