Overview
ℹī¸
Berkeley 35 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old 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.
Distant Low extinction Near-solar metallicity Old

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
