Overview
HSC 2703 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~7.58 kpc) differs significantly from the median photometric distance (~4.96 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
