Overview
CWNU 1229 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~0.93 kpc) differs significantly from the median photometric distance (~1.34 kpc).
