Overview

ℹ️

ASCC 66 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is very well-studied in the literature.

Close Low extinction Near-solar metallicity Young
