	'''Bó Dù''' (帛度, “Textile Ruler”) is a Chinese asterism consisting of two stars, established by the Wuxian (巫咸) tradition during the Han dynasty. Together with [[Tusi]], the Butcher Shop, it formed a double-asterism within the Chinese super-constellation of [[Tianshi (天市)]], the Celestial Market Place. Since 2025, "Bodu" is also the IAU-star name of 95 Her, a white subgiant in the constellation of [[Hercules]].

	In the [https://ui.adsabs.harvard.edu/abs/1991bsc..book.....H/abstract Bright Star Catalog (Hoffleit & Jaschek 1991)], 95 Her refers to a binary of two bright stars: 95 Her A (HR 6730, HD 164669; Vmag=4.96) and 95 Her B (HR 6729, HD 164668; Vmag=5.18). The pair appear together in the Hipparcos catalog with designation HIP 88267, and in the Washington Double Star catalog as STF 2264 (WDS J18015+2136), with the separation recently measured to be 6.3 arcseconds. [https://ui.adsabs.harvard.edu/abs/1987ApJS...65..581G/abstract Gray & Garrison (1987)] reported spectral types for the 95 Her A and B components of A2IV and G5III, respectively. 95 Her A is is somewhat brighter in the V-band, but 95 Her B is brighter in the infrared and actually has a higher bolometric luminosity and mass (it is the slightly more massive, and evolved of the two stars). Using Gaia astrometry [https://ui.adsabs.harvard.edu/abs/2022A%26A...657A...7K/abstract Kervella et al. (2022)] estimated the pair to be separated by 6.37", corresponding to 840 astronomical units, and their tangential velocities agree within 1.23+-0.05 km/s. No orbit for the pair has been published yet, which is unsurprising, as since the ~~pair was discovered~~ in 1780, the separation has barely changed, and the position angle has only changed by about 9 degrees.

[https://ui.adsabs.harvard.edu/abs/1987ApJS...65..581G/abstract Gray & Garrison (1987)] reported spectral types for the 95 Her A and B components of A2IV and G5III, respectively. The vivid color contrast of the pair was noted in the 19th century, with [https://books.google.com/books?id=ZzI6bIuzfp0C&pg=PA299&dq=%2295+Herculis%22 William Henry Smyth] reporting A to be "greenish" and B to be "cherry red" (1833) and then later in his life as "pale green" and "reddish", meanwhile his contemporary Benedict Sestini reported both to be "gold yellow".

			95 Her A is is somewhat brighter in the V-band, but 95 Her B is brighter in the infrared and actually has a higher bolometric luminosity and mass (it is the slightly more massive, and evolved of the two stars). Using Gaia astrometry [https://ui.adsabs.harvard.edu/abs/2022A%26A...657A...7K/abstract Kervella et al. (2022)] estimated the pair to be separated by 6.37", corresponding to 840 astronomical units, and their tangential velocities agree within 1.23+-0.05 km/s. No orbit for the pair has been published yet, which is unsurprising, as since the first report of the binary by William Herschel in 1780 (the year before he discovered Uranus), the separation has barely changed, and the position angle has only changed by about 9 degrees. [http://stars.astro.illinois.edu/sow/95her.html Jim Kaler] estimates the orbital period to be at least 11,000 years.

	Following IAU WGSN policy, names are adopted for individual stars, and when the star turns out to be multiple, the name defaults to that of the primary star (usually the brighter of the two in the V band, where measured). The WGSN may later adopt other cultural/historical names for companions.

	In this case, the name Bodu has been adopted by IAU WGSN specifically for the brighter (in the visible) of the pair: 95 Her A (HR 6730, HD 164669, HIP 88267 A), a hot white subgiant of 2.8 solar masses at a distance of 432 light years.
