Overview

ℹ️

CWNU 1551 is a sparse, dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~4.71 kpc) differs significantly from the median photometric distance (~3.55 kpc).
