Overview

ℹ️

CWNU 4209 is a sparse, loose object of low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

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

(*): The parallax distance estimate (~6.64 kpc) differs significantly from the median photometric distance (~4.90 kpc).
