Overview

ℹ️

MCM 74 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.

⚠️ 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.

Distant

Morales et al. (2013)
Classified as morphological type 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded, presence of emission related to PAH or warm dust.

Mercer et al. (2005)
Cluster of stars. Associated with mid-IR extended emission.
