  The Double Cluster is located in the constellation of Perseus and consists of two open clusters, NGC 869 and NGC 884. The clusters are separated from each other by 100's of light years and are at a distance from us of approximately 7,500 light years. The clusters are relatively young with both being 12.8 million years old. Located within each cluster are 300 blue-white super-giant stars. The clusters are also blue shifted, with NGC 869 and NGC884 approaching us at a speed of 24 miles/sec.
