NGC4755 Jewel Box in Crux

        Object type:             Open Star Cluster

        Distance from Earth:      7,600 light years / 2340 parsecs


        The Jewel Box was so named because of the stark contrast between
        Kappa Crucis and the other stars in the cluster.  Kappa is a 
        bright red star, surrounded by blue and white stars of different
        color and intensity.
