Overview

ℹ️

CWNU 4456 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by high extinction. It is catalogued as a very 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 (~7.57 kpc) differs significantly from the median photometric distance (~12.88 kpc).
