Overview

â„šī¸
Dias 8 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature, with no articles listed in the last 7 years.

(*): The parallax distance estimate (~3.44 kpc) differs significantly from the median photometric distance (~2.24 kpc).

âš 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.

Relatively close Low extinction Old
