Overview

ℹ️

Ruprecht 17 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a low-mass, metal-rich, intermediate-age cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is moderately studied in the literature.
