Arp 216 consists of
NGC 7679 (PGC 71554, UGC 12618, VV 329/a and others) near the center and
NGC 7682 (PGC 71566, UGC 12622, VV 329b and others), the barred spiral to the left (east). While considered interacting galaxies,
NGC 7679 is located approximately 187 million light-years away but
NGC 7682 is at 238 million light-years. Taking a second look, they are much closer if I use the same source. I tend to use the newest one. Found in Arp’s “Galaxies (not classifiable as S or E): Adjacent loops” class, both are found in Pisces.
UGC 12628 (PGC 71578 and others) is the spiral at the bottom left. It is located approximately 124 million light-years away.
