Seznam galaksij z najštevilčnejšimi sistemi kroglastih kopic
Videz
To je seznam galaksij z najštevilčnejšimi znanimi sistemi kroglastih kopic. Leta 2019 je imela najštevilčnejši sistem galaksija NGC 6166, saj je imela kar 39 000 kroglastih kopic.[1] Ostale galaksije s številčnimi sistemi so NGC 4874, NGC 4889, NGC 3311 in Messier 87. Za primerjavo: Rimska cesta ima redek sistem kroglastih kopic; ima jih namreč samo 150-180.
