Overview

ℹ️

Berkeley 92 is a rich, dense object of high C3 quality. Its parallax locates it at a large distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Very distant Moderate extinction Massive Near-solar metallicity Old Contains BSS
