Overview

ℹ️

Berkeley 100 is a rich, very dense object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~6.08 kpc) differs significantly from the median photometric distance (~4.30 kpc).
