Overview

ℹ️

Ruprecht 49 is a moderately populated, loose object of intermediate 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 poorly studied in the literature.

(*): The parallax distance estimate (~2.72 kpc) differs significantly from the median photometric distance (~1.82 kpc).

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