How far away are the constellations

Constellations are not true associations of stars; they merely help us find our way around the sky. Our ancestors arranged groups of bright stars more or less arbitrarily to form images. For this reason there is no answer to the question of how far away a constellation is. The stars in a constellation are situated at varying distances from Earth. For example, the seven brightest stars in the Great Bear are between 55 and 93 light-years away, and the star with the designation Kappa in the Great Bear’s front paw is 200 light-years away.
         The name of the Great Bear constellation comes from Greek Mythology-Zeus transformed the nymph Cellisto into a bear and placed her in the sky.
