Overview

ℹ️

CWNU 2954 is a poorly populated, loose object of very high C3 quality. Its parallax locates it at a very large^* distance, well below the mid-plane, affected by low 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 (~11.43 kpc) differs significantly from the median photometric distance (~8.71 kpc).
