Overview

ℹ️

Ruprecht 80 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.86 kpc) differs significantly from the median photometric distance (~2.34 kpc).

Relatively close Low extinction Near-solar metallicity Intermediate age
