Overview

ℹ️

Teutsch 42 is a poorly populated, loose object of 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 very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.44 kpc) differs significantly from the median photometric distance (~2.00 kpc).

Relatively close Very high extinction Very young

Mercer et al. (2005)
Association of stars. Detected using no magnitude cut. Detected in 2MASS catalog with our algorithm. Appears in 2MASS images.

Morales et al. (2013)
Classified as morphological type 'OC1' (totally exposed cluster still physically associated with gas). Morphological flag: exposed cluster, without submm emission.
