Overview

â„šī¸
HSC 2112 is a poorly populated, very dense object of intermediate 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-rich, 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 2 later reported entries. See table with shared members information.
