Hyades and Pleiades star clusters. Optical photograph of the Hyades and Pleiades star clusters in the constellation Taurus. North is at top. The Hyades form a V-shape at lower left. The cluster contains over 200 stars, of which several are visible to the naked eye. The bright star Aldebaran (Alpha Tauri) seen in the cluster is not actually a member at all, lying around half the distance to the cluster at around 60 light years. The Pleiades cluster (upper right) is young in astronomical terms, around 100 million years old. The cluster lies 380 light years away, and is thought to contain over 500 stars.
