Overview
ℹī¸
Ruprecht 167 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above 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 metallicity parameter (see Parameters). It is very well-studied in the literature.
Relatively close Moderate extinction Near-solar metallicity Intermediate age
