Overview
HSC 2580 is a sparse, very dense object of very high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by high extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~5.37 kpc) differs significantly from the median photometric distance (~3.54 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
