CWNU 1876
- CN 0.0 Sparse
- Cdens 0.17 Very loose
- CC3 0.5 Intermediate quality
- Clit 0.0 Rarely studied
- Cdup 1.0 Unique
Overview
CWNU 1876 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a moderate* distance, above the mid-plane. It is catalogued as a young cluster (see Parameters). It was recently reported in the literature. (*): The parallax distance estimate (~3.23 kpc) differs significantly from the median photometric distance (~2.45 kpc).
Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
