Overview
ℹī¸
ASCC 111 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is very well-studied in the literature.
Close Low extinction Massive Near-solar metallicity Young
