'''G Scorpii''' (abbreviated '''G Sco'''), also named '''Fuyue''' {{IPAc-en|'|f|uː|juː|eɪ}}<!--the anglicized pronunciation of "Yue" is YOO-ay.-->,<ref name="IAU-LSN">{{cite web | url=https://www.iau.org/public/themes/naming_stars/ | title=Naming Stars |publisher=IAU.org |accessdate=16 December 2017}}</ref> is a [[star]] in the [[constellation]] of [[Scorpius]]. It has an [[apparent magnitude]] of +3.19. It is approximately 126 [[light-year]]s from the [[Sun]].<ref name=aaa474_2_653/>

== Nomenclature ==

''G Scorpii'' is the star's [[Bayer designation]]. (It was formerly situated in the constellation of [[Telescopium]] where it was designated ''γ&nbsp;Telescopii'' ([[Latinisation of names|Latinised]] to ''Gamma Telescopii''). It was resited in Scorpius and redesignated G Scorpii by [[Benjamin Apthorp Gould|Gould]].<ref>{{cite book

It bore the [[traditional Chinese star names|traditional name]] ''Fuyue'' ({{zh|s=傅说|t=傅說}}）in ancient [[China]]. [[Fu Yue]] was a former slave that became a high-ranking minister to [[Shang dynasty]] ruler, [[Wu Ding]]. G Scorpii is a member of the [[Tail (Chinese constellation)|Tail]] mansion (尾宿, [[pinyin]]: Wěi Xiù), one of the [[Twenty-Eight Mansions|twenty-eight mansions]] of the [[Chinese constellations]]. In 2016, the IAU organized a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN)<ref name="WGSN">{{cite web | url=https://www.iau.org/science/scientific_bodies/working_groups/280/ | title=IAU Working Group on Star Names (WGSN)|accessdate=22 May 2016}}</ref> to catalog and standardize proper names for stars. The WGSN approved the name ''Fuyue'' for this star on 30&nbsp;June 2017 and it is now so included in the List of IAU-approved Star Names.<ref name="IAU-LSN"/>

== Properties ==

G Scorpii is an orange [[stellar classification#Class K|K-type]] [[giant star|giant]]. The measured [[angular diameter]] is {{nowrap|3.94 ± 0.21 [[Minute and second of arc#Symbols and abbreviations|mas]]}}.<ref name=aaa431_773/> At the estimated distance of this system, this yields a physical size of about 16 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/>

Just 8.5 [[Minute and second of arc|arcminutes]] to the east is the [[globular cluster]] [[NGC 6441]].
