The other Zwicky's Triplet
editIC 3481 at 12h 32m, +11° 24' (2000.0) in Virgo, which is connected to PGC 41646 ("IC 3481A") as the system Arp 175, but probably not connected to IC 3483, is sometimes called Zwicky's Triplet, but this name is more often applied to the system at 16h 49m, +45° 30' (2000.0) in Hercules.[6][7]
