Overview

ℹ️

Berkeley 14A is a poorly populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is moderately studied in the literature.
