Overview

ℹ️

CWNU 216 is a poorly populated, very dense object of very 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 very metal-poor, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is rarely studied 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.
