Overview
ℹī¸
IC 5146 is a rich, very dense object of very high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is very well-studied in the literature.
Close Moderate extinction Near-solar metallicity Very young
