Overview

ℹ️

CWNU 4286 is a sparse, very loose object of high C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by very high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~11.71 kpc) differs significantly from the median photometric distance (~7.41 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.
