Overview

ℹ️

Bochum 5 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~3.55 kpc) differs significantly from the median photometric distance (~1.77 kpc).
