Overview

ℹ️

Ruprecht 152 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

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