Overview

ℹ️

HSC 2332 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~5.46 kpc) differs significantly from the median photometric distance (~4.13 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
