Overview
NGC 1252 is a poorly populated, moderately dense object of very low C3 quality. Its parallax locates it at a close distance, well below the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 9 years.
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.

Cantat-Gaudin et al. (2020)
Long debated object; multiple studies disagree on its reality. Gaia DR2 and spectroscopic data show no coherent kinematic group. Currently considered an asterism or non-physical object. More details in Appendix A of the article.
