FSR 1757
(MWSC 2869)
- CN 0.0 Sparse
- Cdens 0.04 Very loose
- CC3 0.12 Very low quality
- Clit 0.31 Poorly studied
- Cdup 1.0 Unique
Overview
(*): The parallax distance estimate (~5.20 kpc) differs significantly from the median photometric distance (~1.40 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.

💡 Note: The parameters are sometimes transformed from their original values to match the format of the columns shown here, see FAQ. The columns DAv, Bfr, BSS correspond to differential extinction, binary fraction, and blue stragglers, respectively. BSS values can be listed as fractions or integers.
