Overview
Ruprecht 129 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by high extinction. It is catalogued as a young cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.25 kpc) differs significantly from the median photometric distance (~1.53 kpc).
β οΈ 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.
