Overview

FSR 1725 is a moderately populated, dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, metal-rich, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~4.76 kpc) differs significantly from the median photometric distance (~2.60 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.

💡 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.
(*): indicates that this parameter is assigned more than one value in the corresponding reference.
