Overview

ℹ️

CWNU 2682 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~4.54 kpc) differs significantly from the median photometric distance (~3.40 kpc).
