Overview

ℹ️

Czernik 12 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is very well-studied in the literature.

Relatively close Low extinction Near-solar metallicity Old
