Overview

ℹ️

NGC 7127 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.12 kpc) differs significantly from the median photometric distance (~1.88 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.

Poorly studied object with highly discrepant age and distance estimates; physical reality uncertain. More details in Appendix A of the article.
