Overview
ℹī¸
UBC 607 is a rich, very dense object of 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, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.
Distant Moderate extinction Massive Near-solar metallicity Old
