Overview
FoF 140 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 moderate extinction. It is catalogued as a massive, near-solar metallicity, very young cluster (see Parameters). It is rarely studied in the literature.
(*): The parallax distance estimate (~3.49 kpc) differs significantly from the median photometric distance (~2.50 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.
