Overview

ℹ️

CWNU 3157 is a moderately populated, loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~5.58 kpc) differs significantly from the median photometric distance (~3.98 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.
