Overview

ℹ️

CWNU 1106 is a sparse, very dense object of very high C3 quality. Its parallax locates it at a very close distance, near 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 absorption and age parameters (see Parameters). It is poorly studied in the literature.

Very close Low extinction Near-solar metallicity Very young
