Overview

ℹ️

CWNU 119 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is rarely studied in the literature.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
