Overview

ℹ️

Teutsch 84 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a very massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is very well-studied in the literature.

Relatively close High extinction Very massive Near-solar metallicity Intermediate age

Almeida et al. (2025)
