The Double cluster in Perseus is a pair of open clusters (NGC 869 and NGC 884) located in the constellation of Perseus. Both are young clusters at an age of around 12.8 million year old, and contain many blue-white super giant stars. The clusters are located 7,500 light years distant and are separated from each other by several hundred light years. They are located in the Perseus arm of the Milky Way Galaxy, while we are located in the Orion arm.
