Overview

ℹ️

FSR 0248 is a moderately populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a metal-poor, extremely old cluster, but with a large variance across recent sources for the distance and age parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~1.73 kpc) differs significantly from the median photometric distance (~6.67 kpc).
