Overview

ℹ️

FSR 1402 is a rich, very dense object of high C3 quality. Its parallax locates it at a large^* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~5.03 kpc) differs significantly from the median photometric distance (~3.84 kpc).
