Messier 34 is a sparse open cluster containing over 100 stars. With an age of about 225 million years, M34 is a rather old cluster. Located about 1,500 light years away in the constellation Perseus, M34 shares properties (such as distance, spatial motion) with other open clusters like M45, NGC 2516, IC 2602, the Delta Lyrae Cluster Lyra, and the Alpha Persei Cluster in Perseus. These properties were discovered in 1983 by Olin Eggen. These clusters are now considered to be related members of the Local Association.
