Overview
ℹ️
Berkeley 94 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young 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.

(*): The parallax distance estimate (~4.49 kpc) differs significantly from the median photometric distance (~3.44 kpc).

Almeida et al. (2025)
Mass determination: good fit. Isochrone match: intermediate fit.

Cavallo et al. (2024)
