Overview

ℹ️

Ruprecht 124 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a very large^* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~21.88 kpc) differs significantly from the median photometric distance (~2.19 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.

Relatively close Moderate extinction Intermediate age
