Vzaimodeistvuyushaya para galaktik, kotoruyu nazyvayut takzhe sistemoi Kinana (v chest' ee pervootkryvatelya) i Arp 104, nahoditsya na rasstoyanii primerno 17 millionov svetovyh let v sozvezdii Bol'shoi Medvedicy. Soedinyayushii ih most, a takzhe vyhodyashaya iz NGC 5218 struktura, pohozhaya na zapyatuyu, i iskazhennaya forma spiral'nyh rukavov NGC 5216 yavlyayutsya sledstviem deistviya gravitacionnyh prilivnyh sil, razrushayushih galaktiki pri povtoryayushihsya sblizheniyah. Cherez neskol'ko milliardov let eti sblizheniya, veroyatno, privedut k ih sliyaniyu v odnu galaktiku.
