Overview
HSC 2102 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~6.35 kpc) differs significantly from the median photometric distance (~4.23 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
