Overview
CWNU 488 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.52 kpc) differs significantly from the median photometric distance (~3.72 kpc).
