Overview

ℹ️

Ruprecht 107 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

(*): The parallax distance estimate (~4.13 kpc) differs significantly from the median photometric distance (~3.12 kpc).
