Overview

ℹ️

Loden 1 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by low extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.70 kpc) differs significantly from the median photometric distance (~0.79 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Close Low extinction Low mass Intermediate age

Cantat-Gaudin & Anders (2020)
Initially proposed as an old nearby cluster, but radial velocity studies show no co-moving group; not physical. More details in Appendix A of the article.
