Overview

ℹ️

CWNU 3966 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by very high extinction. It is catalogued as a young cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~7.66 kpc) differs significantly from the median photometric distance (~4.37 kpc).
