Overview
HSC 723 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 a massive, metal-rich, young cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~10.46 kpc) differs significantly from the median photometric distance (~6.96 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.
