Overview
FSR 1703 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.05 kpc) differs significantly from the median photometric distance (~1.57 kpc).
Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
