Overview

ℹ️

CWNU 3151 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~8.23 kpc) differs significantly from the median photometric distance (~6.31 kpc).
