Overview

ℹ️

CWNU 4006 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~7.28 kpc) differs significantly from the median photometric distance (~12.59 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.
