Overview

ℹ️

CWNU 396 is a sparse, moderately dense object of very low C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a very metal-poor, young cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~0.87 kpc) differs significantly from the median photometric distance (~1.29 kpc).

⚠️ 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.
