Overview

ℹ️

Teutsch 38 is a rich, very dense object of very high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is very well-studied in the literature.

Close Low extinction Near-solar metallicity Young
