Overview

FSR 1736 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as an extremely massive, very old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.11 kpc) differs significantly from the median photometric distance (~7.47 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.

Very distant Moderate extinction Extremely massive Very old

💡 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.
