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 metal-rich, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~6.12 kpc) differs significantly from the median photometric distance (~2.02 kpc).

Relatively close Very high extinction Metal-rich Young

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.

Cavallo et al. (2024)
Wood sample.
