HXWHB 9
- CN 0.0 Sparse
- Cdens 0.06 Very loose
- CC3 0.38 Low quality
- Clit 0.0 Rarely studied
- Cdup 1.0 Unique
Overview
HXWHB 9 is a sparse, very loose object of low C3 quality. Its parallax locates it at a close distance, near the mid-plane. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 6 years. 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.
