Overview

ℹ️

Ruprecht 12 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, well below the mid-plane, affected by low extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.03 kpc) differs significantly from the median photometric distance (~0.90 kpc).
