869 and NGC 884 - the Double Cluster - lie 7,500 light years away
in the constellation of Perseus. They are relatively young (12.8
million years old) and contain more than 300 super-giant stars.
Both clusters are blue-shifted, meaning that they are approaching
us vs. moving away. In this case, the rate of approach is 24 miles-per-second.
