Overview

ℹ️

DBSB 90 is a poorly populated, loose object of 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.

(*): The parallax distance estimate (~2.49 kpc) differs significantly from the median photometric distance (~9.38 kpc).

Note: This is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry, and a very small percentage with at least one entry reported in the same catalogue. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.91) 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 'EC2' (partially embedded cluster). Morphological flag: cluster partially embedded, presence of emission related to PAH or warm dust.
