Overview

ℹ️

CWNU 4274 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* 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 (~4.05 kpc) differs significantly from the median photometric distance (~3.02 kpc).
