HD 153072, also named Shengong, is a binary star system in the constellation Scorpius, about 360 light-years (110 parsecs ) distant. With an apparent magnitude of 6.05, it is very faintly visible to the naked eye under ideal viewing conditions. Both components are A-type stars; [4] sources differ as to the luminosity class, some listing it as a main-sequence star [3] and others as a giant star. [1] The two stars orbit with a period of 38 years. [3]
In Chinese astronomy, Shéngōng (simplified Chinese :神宫; traditional Chinese :神宮, "Divine Palace") is a single-star asterism associated with the lunar mansion Wěi (Tail). It has variously been identified as the star μ2 Scorpii (Pipirima); the star cluster NGC 6231; or another faint star or patch of stars near μ2, embedded in clouds of the Milky Way. In the latter case, the position in old star catalogues most closely corresponds to this star, HIP 83100. [6] The IAU Working Group on Star Names approved the name Shengong for this star on 16 October 2025 and it is now so entered in the IAU Catalog of Star Names. [7]
