Overview

ℹ️

MCM 54 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 (~2.59 kpc) differs significantly from the median photometric distance (~9.38 kpc).

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.88) 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 'OC0' (emerging exposed cluster). Morphological flag: possibly associated submm emission surrounding the cluster, presence of an IR bubble.

Mercer et al. (2005)
Association of stars. Associated with mid-IR extended emission. Detected in 2MASS catalog with our algorithm. Appears in 2MASS images.
