Overview
FSR 1694 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~0.80 kpc) differs significantly from the median photometric distance (~1.15 kpc).
Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
