Overview

ℹ️

Berkeley 72 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.

(*): The parallax distance estimate (~6.09 kpc) differs significantly from the median photometric distance (~4.20 kpc).
