Object Information:

 

Messier 52, NGC 7654
Distance -  Estimates range from 3,000 to 7,000 light years

The dense grouping of stars in the image above is known as an open cluster [sometimes also known as a "galactic cluster"].   Open clusters are believed to originate in the same general area of space from the same local gas clouds.  The dense grouping of stars seen above are all about the same approximate distance from us.  It is believed that eventually the component stars of open clusters slowly drift apart and disperse.
