Overview

ℹ️

HSC 567 is a moderately populated, very loose object of high C3 quality. Its parallax locates it at a very large distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

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