Object name: NGC5297
Designation(s): NGC5297, NGC5296,
Yet another interesting, apparently connected, galaxy pair amateurs ignore. NGC 5296 and NGC 5297 are a pair of interacting galaxies that Arp was well aware of yet, for some reason, didn't include in his atlas. I'll get to the Arp connection in a bit. This interacting pair is located in northeastern Canes Venatici at a distance of about 110 to 120 million light-years. Though one non-redshift measurement of NGC 5297 puts it nearly a billion light-years away I think we can safely consider that an anomalous result. The pair is sometimes likened to M31 and NGC 205 (M110). NGC 5297 is a large SAB(s)c spiral about 170,000 light-years across thanks to its wide but sparse arms. NGC 5297 was discovered by William Herschel on April 9, 1787 but its companion had to wait until George Stoney working for the Earl of Rosse found it on May 3, 1850. NGC 5297 isn't in either Herschel 400 list but maybe it should be.
