Overview

ℹ️

Aveni Hunter 1 is a rich, very dense object of very high C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low 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.

Very close Low extinction Near-solar metallicity Very young
