Pleione is an outlying star on the eastern edges of the Pleiades cluster, with the main body of the cluster falling to its west (or right, in this image). The nearby brighter star to Pleione's immediate south is Atlas (or 27 Tauri), named for Pleione's husband in Greek mythology. Imagery provided by Aladin sky atlas

In mythology, Pleione was the mother of the Pleiades; she and her husband Atlas have stars named for them in their daughters' cluster, lying slightly to the east of the main grouping of stars. Like all the Pleiades, Pleione is a young blue star. It appears to be somewhat unstable, and has been observed to throw off shells of material at intervals of several decades.
