Overview

â„šī¸
CWNU 3075 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a very large* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~29.76 kpc) differs significantly from the median photometric distance (~11.48 kpc).

âš 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.
