Description:

A fine star cluster of the "open" or "galactic" type, located in a rich Milky Way field on the western edge of the constellation, near the Cepheus border. M52 is one of the richer and more compressed clusters with a computed density of somewhat over 3 stars per cubic parsec, rising to more than 50 stars per cubic parsec near the cluster center. In terms of age, it appears to be among the younger open clusters, probably comparable in age and type to the Pleiades. The brightest main sequence stars are blue giants of spectral type B7.
