Overview

ℹ️

CWNU 2871 is a moderately populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-rich, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported 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.
