Overview

ℹ️

CWNU 3031 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a very large^* distance, below the mid-plane, affected by high extinction. It is catalogued as an old 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 (~12.02 kpc) differs significantly from the median photometric distance (~6.92 kpc).
