Overview

ℹ️

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

(*): The parallax distance estimate (~4.84 kpc) differs significantly from the median photometric distance (~3.38 kpc).
