| '''Rho Andromedae''' (ρ And, ρ Andromedae) is the [[Bayer designation]] for a [[star]] in the northern [[constellation]] of [[Andromeda (constellation)|Andromeda]]. It has an [[apparent visual magnitude]] of +5.19,<ref name=aj73_84/> which, according to the [[Bortle Dark-Sky Scale]], is bright enough to be seen with the naked eye from dark suburban skies. Based upon [[parallax]] measurements, this star is at a distance of approximately {{Convert|158|ly|pc|abbr=off|lk=on}} from [[Earth]].<ref name=aaa474_2_653/> | |
| | |
| The [[stellar classification]] of this star is F5 III,<ref name=SIMBAD/> indicating that it is in the [[giant star|giant]] stage of its [[stellar evolution]]. However, some sources list a classification of F5 IV,<ref name=apjss176_1_276/><ref name=SIMBAD/> suggesting that it may still be in the [[subgiant star|subgiant]] stage. The [[interferometry]]-measured [[angular diameter]] of this star is {{nowrap|0.626 [[milliarcseconds|mas]]}},<ref name=apjss176_1_276/> which, at its estimated distance, equates to a physical radius of around 3.3 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/> The [[stellar atmosphere|outer envelope]] is radiating around 20<ref name=apjss176_1_276/> times the luminosity of the Sun into space at an [[effective temperature]] of 6,471 K,<ref name=apj354/> giving it the yellow-white hue of an F-type star.<ref name=csiro/> It is about 1.3 billion years old.<ref name=aaa418_989/>
| |
| | |
| X-ray emissions were detected from this star during the [[EXOSAT]] mission.<ref name=aaa174_1_187/>

| ==Naming==
| |
| In [[Chinese language|Chinese]], {{lang|zh|天廄}} ({{lang|zh-Latn|Tiān Jiù}}), meaning ''[[Wall (Chinese constellation)|Celestial Stable]]'', refers to an asterism consisting of ρ Andromedae, [[Theta Andromedae|θ Andromedae]] and [[Sigma Andromedae|σ Andromedae]]. Consequently, ρ Andromedae itself is known as {{lang|zh|天廄二}} ({{lang|zh-Latn|Tiān Jiù èr}}, {{lang-en|the Second Star of Celestial Stable}}.)<ref>{{zh icon}} [http://aeea.nmns.edu.tw/2006/0605/ap060518.html AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 5 月 18 日]</ref>
