Overview
ℹī¸
ESO 141 47 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate* distance, well below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.20 kpc) differs significantly from the median photometric distance (~2.29 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.

Dias et al. (2022)
Likely not a real open cluster.
