Overview

ℹ️

OC 0146 is a moderately populated, loose object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, young cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is rarely studied in the literature.
