Overview

ℹ️

CWNU 3145 is a moderately populated, very dense 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 an intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~6.02 kpc) differs significantly from the median photometric distance (~4.37 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.
