Overview
CWNU 1240 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a close* distance, above 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 (~0.94 kpc) differs significantly from the median photometric distance (~1.40 kpc).
