Etymology and History

Tusi and Bodu on Dunhuang Star Map

WGSN star name "Tusizuo", profile card, created by M. Sadegh Faghanpour (IAU WGSN).

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.
