Overview
ℹī¸
Dol Dzim 4 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.71 kpc) differs significantly from the median photometric distance (~1.66 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.
