Overview

ℹ️

G3CC 40 is a sparse, very loose object of very 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.

Note: This is a unique object, which shares a very 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=0.96) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Classified as morphological type 'EC1' (deeply embedded cluster). Morphological flag: cluster fully embedded.
