Overview

ℹ️

Berkeley 25 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, well below the mid-plane, affected by moderate extinction. It is catalogued as an extremely massive, near-solar metallicity, very old cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is well-studied in the literature.

Very distant Moderate extinction Extremely massive Near-solar metallicity Very old
