Overview

ℹ️

VVV 028 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, above 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.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~3.93 kpc) differs significantly from the median photometric distance (~6.10 kpc).

Very distant

Morales et al. (2013)
Classified as morphological type 'OC1' (totally exposed cluster still physically associated with gas). Morphological flag: exposed cluster, without submm emission, presence of an IR bubble.
