Overview

ℹ️

CWNU 5 is a moderately populated, very loose object of high C3 quality. Its parallax locates it at a very close^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~0.48 kpc) differs significantly from the median photometric distance (~0.72 kpc).

Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
