Overview

ℹ️

CWNU 463 is a moderately populated, dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near 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 absorption, age, and metallicity parameters (see Parameters). It is poorly studied in the literature.
