Overview

ℹ️

Pismis 22 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~6.12 kpc) differs significantly from the median photometric distance (~3.70 kpc).
