Overview

ℹ️

CWNU 4040 is a moderately populated, moderately dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

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

(*): The parallax distance estimate (~4.40 kpc) differs significantly from the median photometric distance (~3.31 kpc).
