Overview

ℹ️

Dias 126 is a sparse, loose object of low C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~7.01 kpc) differs significantly from the median photometric distance (~4.87 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.
