Overview

ℹ️

G3CC 18 is a sparse, moderately dense object of intermediate 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 'EC1' (deeply embedded cluster). Morphological flag: cluster fully embedded.
