The galactic position of the Double Cluster, Chi/h Persei. The h cluster is a little
nearer to Earth than the Chi element, but on the scale of this diagram, the two clusters
effectively occupy the same space.
A famous pairing of relatively bright open clusters in the constellation of Perseus. Though
both clusters are distant from Earth (more than 7,000 light years), they lie less
than one hundred light years from one another.
