Overview

ℹ️

DBSB 104 is a sparse, loose object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is moderately studied in the literature.
