Overview

ℹ️

DBSB 36 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a metal-rich, young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~1.76 kpc) differs significantly from the median photometric distance (~1.18 kpc).
