Overview

ℹ️

DB2001 22 is a poorly populated, loose 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 poorly studied in the literature.

Distant Very high extinction Near-solar metallicity Very young
