Overview
ℹ️
Berkeley 104 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is very well-studied in the literature.

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

Distant Moderate extinction Near-solar metallicity Intermediate age Contains BSS
