Shengong (神宫, Divine Palace) is a subsidiary asterism attached to the lodge Wěi (尾), located to the left of its determinative star and consisting of only a single star.
Concordance, Etymology, History
Shengong represents the intimate chamber shared by the emperor and his consorts; for a detailed discussion of its symbolism and origin, see the entry Wěi (尾).
The asterism is mentioned only in some of the historical sources: two maps and a star catalog.
The coordinates given in the star catalog are: " ... "
The position would identify with the star HIP 83100 which has only 6.05 mag (V). The star HIP 83491 is a bit further east but also a bit brighter (5.9 mag in V).
Identification of stars
According to the Kaiyuan zhanjing (Divination Canon of Kaiyuan Reign, KYZJ, compiles between 712–718 CE), Shengong corresponds to μ² Scorpii. However, in later periods some astronomers identified it with other stars. For instance, the Jingyou Star Catalogue (compiled in 1034 CE by Yang Weide) placed Shengong roughly one degree away from the determinative star, which may correspond to HIP 83000 (barely visible after atmospheric extinction) or the slightly brighter HIP 83491. In the Qing dynasty, astronomers further associated it with the open cluster NGC 6231.

Star Name Discussion (IAU)
In 2025, the name of the historical constellation "Shengong" was suggested to be used for one of the stars in this constellation. As mu2 Sco was named as Pipirima already, it is proper to apply Shengong to HIP 83491, a 5.9 mag star in Scorpius.
