    This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud . There are over 1,000 known open clusters in the Milky Way galaxy, but the actual total may be up to ten times higher. [ 1 ]
