Overview

ℹ️

DBSB 158 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age 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.

Relatively close Moderate extinction Intermediate age

Morales et al. (2013)
Classified as morphological type 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded, presence of emission related to PAH or warm dust.
