Overview
ℹī¸
ESO 128 16 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate* distance, above the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.50 kpc) differs significantly from the median photometric distance (~0.97 kpc).

⚠ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
