Overview
HSC 320 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~4.32 kpc) differs significantly from the median photometric distance (~3.16 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
