Overview

ℹ️

FSR 0320 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, above 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 metallicity parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.20 kpc) differs significantly from the median photometric distance (~4.72 kpc).

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