| '''Zeta Apodis''' (ζ Aps, ζ Apodis) is the [[Bayer designation]] for a [[star]] in the southern [[constellation]] of [[Apus]]. It has an [[apparent visual magnitude]] of +4.78,<ref name=clpl4_99/> 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 {{Convert|297|ly|pc|abbr=off|lk=on}}.<ref name=aaa474_2_653/>
| |
| | |
| The [[spectrum]] of Zeta Apodis matches a [[stellar classification]] of K2 III,<ref name=houk1978/> with the [[luminosity class]] of III indicating it is an [[stellar evolution|evolved]] [[giant star]]. The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap|2.06 ± 0.02 [[milliarcsecond|mas]]}}.<ref name=aaa431_773/> At the estimated distance of Eta Draconis,<ref name=aaa474_2_653/> this yields a physical size of about 11 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/> The [[stellar atmosphere|outer atmosphere]] has an [[effective temperature]] of 4,388 K,<ref name=aaa339_858/> which gives it the orange-hued glow of a [[K-type star]].<ref name=csiro/>

| In [[Chinese language|Chinese]] caused by adaptation of the European southern hemisphere constellations into the Chinese system, {{lang|zh|異雀}} ({{lang|zh-Latn|Yì Què}}), meaning ''[[Chinese constellations#The Southern Asterisms|Exotic Bird]]'', refers to an asterism consisting of ζ Apodis, [[Iota Apodis|ι Apodis]], [[Beta Apodis|β Apodis]], [[Gamma Apodis|γ Apodis]], [[Delta Octantis|δ Octantis]], [[Delta Apodis|δ<sup>1</sup> Apodis]], [[Eta Apodis|η Apodis]], [[Alpha Apodis|α Apodis]] and [[Epsilon Apodis|ε Apodis]]. Consequently, ζ Apodis itself is known as {{lang|zh|異雀一}} ({{lang|zh-Latn|Yì Què yī}}, {{lang-en|the First Star of Exotic Bird}}.)<ref>{{zh icon}} [http://aeea.nmns.edu.tw/2006/0607/ap060729.html AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 7 月 29 日]</ref>

Hello. Allow me introduce the author. Her home std test kit name is Emilia Shroyer but it's home std test not the most female title std testing at home out there. To do aerobics is a thing that I'm completely addicted to. Since she was eighteen she's been working as a receptionist but her promotion never over the counter std test arrives. Puerto Rico std testing at home is where he's usually been living but she needs to transfer because of her family members.
