Overview
ℹī¸
Ruprecht 49 is a moderately populated, very dense 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 moderately 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.
