Overview
IC 2156 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
