Overview
ℹī¸
UPK 113 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.
