Overview
UFMG 22 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, below 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 metallicity parameter (see Parameters). It is poorly studied in the literature.
