Overview
FSR 0022 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large* distance, above the mid-plane, affected by very high extinction. It is catalogued as a very massive, old cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~5.82 kpc) differs significantly from the median photometric distance (~4.34 kpc).

💡 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.
