Overview

ℹ️

CWNU 1083 is a rich, 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 parameter (see Parameters). It is poorly studied in the literature.

Note: This object shares a large percentage of members with 2 later reported entries. See table with shared members information.
