Overview
ℹī¸
ESO 493 03 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.58 kpc) differs significantly from the median photometric distance (~1.40 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.
