Overview

ℹ️

CWNU 2223 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
