Overview

ℹ️

Ruprecht 59 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by low extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.70 kpc) differs significantly from the median photometric distance (~2.14 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
