Overview
ℹī¸
UPK 562 is a moderately populated, dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is moderately studied in the literature.
Close Low extinction Near-solar metallicity Intermediate age
