Overview
FSR 1178 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~1.15 kpc) differs significantly from the median photometric distance (~1.76 kpc).
Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
