Overview

ℹ️

NGC 7084 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, well below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 7 years.

(*): The parallax distance estimate (~3.06 kpc) differs significantly from the median photometric distance (~1.26 kpc).

⚠️ 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 Low extinction Old

Cantat-Gaudin & Anders (2020)
Marked non-existent. Proper-motion analysis confirms lack of a physical cluster. More details in Appendix A of the article.
