Overview
ℹī¸
NGC 1579 is a rich, very dense object of high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.
Close High extinction Near-solar metallicity Very young
