Overview

ℹ️

OC 0537 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is rarely studied in the literature.
