Overview

ℹ️

Berkeley 51 is a rich, very dense object of high C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~6.41 kpc) differs significantly from the median photometric distance (~4.50 kpc).
