Location of Aldebaran

Aldebaran is the unmistakable bright 'eye' in the face of Taurus the Bull. Most of the stars in this busy region belong to the cluster known as the Hyades, but orange Aldebaran does not: it is about 100 light years nearer to Earth than the stars of the Hyades cluster.

A prominent orange giant, the 'eye' of the constellation Taurus. Its name means 'the follower', because it follows the Pleiades across northern winter skies.
