Overview
ℹī¸
Ruprecht 132 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

(*): The parallax distance estimate (~1.92 kpc) differs significantly from the median photometric distance (~1.39 kpc).

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