Overview

ℹ️

ESO 435 17 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, well above the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature.

⚠️ 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.
