Overview
HSC 2977 is a poorly populated, dense object of very high C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~2.62 kpc) differs significantly from the median photometric distance (~1.95 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
