Overview
HSC 2173 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
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.
