Overview

ℹ️

CWNU 182 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a close distance, above 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 poorly studied in the literature.

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