In astronomy, the Seven Sisters (Pleiades), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The name of the Pleiades comes from Ancient Greek. The Pleiades were daughters of an Amazonian queen; their names were Maia, Coccymo, Glaucia, Protis, Parthenia, Stonychia, and Lampado. They were credited with inventing ritual dances and nighttime festivals.
