Overview
CWNU 4686 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate* 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 (~3.81 kpc) differs significantly from the median photometric distance (~2.88 kpc).
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
