Overview

ℹ️

FSR 0369 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~0.92 kpc) differs significantly from the median photometric distance (~2.88 kpc).

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