Comment:
The Double Cluster is the common name for the naked-eye open
clusters NGC 884 and NGC 869, which are close together in the
constellation Perseus. NGC 884 and NGC 869 are at distances of 7600
and 6800 light-years away, respectively, so they are close to one
another in space as well. They are relatively young clusters, with
NGC 869 5.6 million years and NGC 884 at 3.2 million years according
to the 2000 Sky Catalogue. (entry source Wikipedia website) |
