Overview

ℹ️

DBSB 21 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.
