Overview

ℹ️

MCM 38 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.

(*): The parallax distance estimate (~2.89 kpc) differs significantly from the median photometric distance (~6.10 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Very distant

Morales et al. (2013)
Classified as morphological type 'OC1' (totally exposed cluster still physically associated with gas). Morphological flag: exposed cluster, without submm emission, presence of an IR bubble and possible YSOs.

Mercer et al. (2005)
Cluster of stars. Appears in 2MASS images.
