NGC 3193 is an elliptical galaxy in the constellation Leo, approximately 58 million light years away . The galaxy belongs together with NGC 3185 , NGC 3187 and NGC 3190 to the compact galaxy group Hickson 44 (HCG 44, Arp 316 (without NGC 3185), NGC 3190 group).
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy triplet belongs to the class of galaxy groups .
It was discovered on March 12, 1784 by the German-British astronomer Wilhelm Herschel . Whether the galaxy belongs to the compact galaxy group HCG 44 located in the immediate vicinity is uncertain and is doubted.
