Stars are sometimes concentrated into tight clusters with a diameter of about ten or twenty light years because the stars all formed in the same nebula. These clusters usually disperse over millions of years although there are some that are more than one billion years old.
Below is a list of the 250 most prominent open clusters in our corner of the Galaxy. Note that because of the relatively large distances to these clusters, that they all tend to have a low galactic latitude.
