Overview

ℹ️

HSC 959 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster (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.
