Overview
ℹī¸
Berkeley 95 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a 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.

Note: This object shares a small percentage of members with 3 later reported entries. See table with shared members information.

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

Cavallo et al. (2024)
Gold sample.
