Overview
ℹī¸
ASCC 6 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is very well-studied in the literature.
Relatively close Low extinction Near-solar metallicity Young
