G Scorpii

G Scorpii (abbreviated G Sco), also named Fuyue, is a giant star in the constellation of Scorpius. It has an apparent magnitude of +3.19. It is approximately 126 light-years from the Sun.
Nomenclature.
"G Scorpii" is the star's Bayer designation. It was formerly situated in the constellation of Telescopium where it was designated "γ Telescopii", Latinised to "Gamma Telescopii". It was resited in Scorpius and redesignated G Scorpii by Gould.
In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN approved the name "Fuyue" for this star on 30 June 2017 and it is now so included in the List of IAU-approved Star Names.
G Scorpii bore the traditional name "Fuyue" (）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 mansion (, pinyin: ), one of the twenty-eight mansions of the Chinese constellations.
Properties.
G Scorpii is an orange K-type giant. The measured angular diameter is . At the estimated distance of this system, this yields a physical size of about 16 times the radius of the Sun. Calculations based on its physical properties give a diameter if about . With an effective surface temperature of , it has a bolometric luminosity of .
Evolutionary models show that G Scorpii has probably left the red giant branch and is now fusing helium in its core. This makes it a red clump star, at the cool end of the horizontal branch.
Just 5 arcminutes to the east is the globular cluster NGC 6441. At magnitude 3.2, G Scorpii is around 40 times brighter than the entire globular cluster.
