Overview

ℹ️

FSR 0022 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by very high extinction. It is catalogued as a very massive, old cluster (see Parameters). It is poorly studied in the literature.

⚠️ 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 Very high extinction Very massive Old

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.
