Overview

ℹ️

Pfleiderer 3 is a rich, very dense object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, metal-poor, old cluster (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~8.87 kpc) differs significantly from the median photometric distance (~5.50 kpc).
