Overview
Platais 5 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a large* distance, well below the mid-plane. It is catalogued as a young cluster (see Parameters). It is poorly studied in the literature, with no articles listed in the last 7 years.
(*): The parallax distance estimate (~5.69 kpc) differs significantly from the median photometric distance (~0.27 kpc).
â 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.
