Overview

ℹ️

Berkeley 48 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 massive, near-solar metallicity, intermediate-age 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.

(*): The parallax distance estimate (~9.23 kpc) differs significantly from the median photometric distance (~6.47 kpc).

Very distant Moderate extinction Massive Near-solar metallicity Intermediate age
