Overview

ℹ️

Czernik 3 is a rich, very dense object of low C3 quality. Its parallax locates it at a moderate distance, near 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 mass parameter (see Parameters). It is well-studied in the literature.

Distant High extinction Near-solar metallicity Intermediate age

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