Overview

ℹ️

Berkeley 52 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is well-studied in the literature.

Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
