Overview

ℹ️

FSR 0823 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.81 kpc) differs significantly from the median photometric distance (~1.10 kpc).

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