Overview

ℹ️

DB2001 22 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.59 kpc) differs significantly from the median photometric distance (~2.50 kpc).

Relatively close Very high extinction Near-solar metallicity Very young
