Overview

ℹ️

UBC 1123 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by low extinction. It is catalogued as a metal-rich, young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is rarely studied in the literature.
