Overview

ℹ️

Mol 99 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a large 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 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=0.81) 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 'EC1' (deeply embedded cluster). Morphological flag: cluster fully embedded.
