Overview
ℹ️
Ruprecht 60 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

Note: This object contains blue stragglers according to at least one source.
