Overview

ℹ️

FSR 0338 is a moderately populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a very massive, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.14 kpc) differs significantly from the median photometric distance (~14.65 kpc).
