Pleione (28 Tauri BU Tauri) is a binary star in the Pleiades star cluster (M45) located roughly 390 light years away in the constellation of Taurus. Pleione was not given a Bayer designation but did receive a Flamsteed number—hence its designation 28 Tauri. Since the star is located close to Atlas it’s difficult for stargazers to distinguish with the naked eye even though it’s a hot type B star 190 times more luminous than the Sun.
