Overview

ℹ️

Berkeley 90 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

Relatively close High extinction Massive Near-solar metallicity Intermediate age
