Overview
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 parameter (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~5.26 kpc) differs significantly from the median photometric distance (~3.92 kpc).
