Overview
HSC 777 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by low extinction. It is catalogued as a metal-poor, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~5.27 kpc) differs significantly from the median photometric distance (~3.79 kpc).
