Overview

ℹ️

CWNU 2167 is a sparse, very loose object of very high C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~7.53 kpc) differs significantly from the median photometric distance (~5.25 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.
