Overview

ℹ️

CWNU 2946 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~11.57 kpc) differs significantly from the median photometric distance (~6.92 kpc).

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
