Overview

ℹ️

HSC 624 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by high extinction. It is catalogued as a metal-rich, young cluster (see Parameters). It was recently reported in the literature.

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
