Collinder 240
- CN 0.0 Sparse
- Cdens 0.03 Very loose
- CC3 0.12 Very low quality
- Clit 0.0 Rarely studied
- Cdup 1.0 Unique
Overview
(*): The parallax distance estimate (~4.07 kpc) differs significantly from the median photometric distance (~1.58 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.
