Overview

ℹ️

Berkeley 56 is a very rich, very dense object of high C3 quality. Its parallax locates it at a very large distance, well below the mid-plane, affected by moderate extinction. It is catalogued as an extremely massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.
