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.)
It bore the traditional name Fuyue (simplified Chinese: 傅说; traditional Chinese: 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 mansion (尾宿, pinyin: Wěi Xiù), one of the twenty-eight mansions of the Chinese constellations. 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 is an orange K-type giant. The measured angular diameter is 3.94 ± 0.21 mas. At the estimated distance of this system, this yields a physical size of about 16 times the radius of the Sun.
