Overview

ℹ️

OC 0416 is a sparse, loose object of intermediate C3 quality. Its parallax locates it at a large distance, well below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old 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.

Very distant Low extinction Near-solar metallicity Old
