Overview
ℹī¸
Ruprecht 53 is a moderately populated, dense object of high C3 quality. Its parallax locates it at a relatively close* 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 (~1.03 kpc) differs significantly from the median photometric distance (~1.52 kpc).

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