Overview

ℹ️

OC 0630 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is poorly studied in the literature.
