Pleione (star)

Pleione, designated 28 Tauri (abbreviated 28 Tau) and BU Tauri, is a binary star and the seventh-brightest star in the Pleiades star cluster (M45) and is located approximately 390 light years from the Sun in the constellation of Taurus. 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. Pleione rotates even faster than Achernar on its axis, close to its breakup velocity.
