Overview

ℹ️

CWNU 3400 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as an intermediate-age cluster (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.

(*): The parallax distance estimate (~4.35 kpc) differs significantly from the median photometric distance (~3.31 kpc).
