Overview

ℹ️

Czernik 44 is a poorly populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.50 kpc) differs significantly from the median photometric distance (~3.45 kpc).
