Tusizuo

Tusi and Bodu on Dunhuang Star Map

Tusizuo is a modern star name adopted to the IAU-Catalog of Star Names in 2025 to memorize the historical constellation Tú Sì (屠肆, "Butcher's Shop").

Etymology and History

The old constellation Tú Sì (屠肆, "Butcher's Shop") is a Chinese asterism consisting of two stars, established by the Wuxian (巫咸) school during the Han dynasty. Among these two stars, one is named "the left" and the other "the right one".

IAU Working Group on Star Names

The constellation name was discussed and approved by the IAU WGSN in 2025. As "Tusi" could be confused with other celestial bodies named Tusi after two Persian astronomers (asteroid (10269) Tusi and asteroid (7058) Al-Tusi), WGSN chose to add a determinative here. The chosen star 95 Her is "the left one in Tusi", in Chinese "Tusizuo", so WGSN adopts this name.
