Arp 296 consists of MCG+10-17-005 (PGC 35345 and others) above and to the left of Arp 299 and PGC 2580146 below it. These also appear to connected by tidal tails although this doesn’t appear to be a certainty. It is possible that these are not even interacting and our view makes it look that way. These are much further away – upwards of 800 million light-years – than Arp 299.
