Pleiades
M45Open Cluster
The nearest and most famous star cluster, known since prehistory. A true family of stars born together about 100 million years ago.
Find it
Look high in the east-southeast on December evenings. Find the bright orange star Aldebaran (the Bull's eye), then continue in the same direction — the Pleiades are the unmistakable fuzzy cluster about 15° northwest. They look like a tiny dipper shape or a small cloud of stars.
