Overview

ℹ️

CWNU 2440 is a sparse, loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a young 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 (~3.50 kpc) differs significantly from the median photometric distance (~2.63 kpc).
