NGC 6166, galaxy with richest known globular cluster system

This is a list of galaxies with richest known globular cluster systems. As of 2019, the galaxy NGC 6166 has the richest globular cluster system, with 39 000 globular clusters.[1] Other galaxies with rich globular cluster systems are NGC 4874, NGC 4889, NGC 3311 and Messier 87. For comparison, the Milky Way has a poor globular cluster system, with only 150-180 globular clusters.
