Overview

ℹ️

CWNU 1185 is a sparse, loose object of high C3 quality. Its parallax locates it at a close^* distance, below the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, young cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is very 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 (~0.68 kpc) differs significantly from the median photometric distance (~0.98 kpc).
