Overview

ℹ️

CWNU 2810 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
