Object name: ARP223
Designation(s): ARP223, NGC7585, NGC7576,
Arp 223 is entered in his catalog under amorphous spiral arms. It is also known as NGC 7585 and is in the constellation of Aquarius just below the Circlet of Pisces. Redshift puts it at about 145 million light-years away. Most sources say it is the result of a merger of two galaxies but do admit they find no hint of the second galaxy saying it must have been some time ago and it is now fully absorbed. They note the presence of NGC 7576 10.7 minutes to the southwest (also in my image) but dismiss it has being too far away. But again admitting that it too is about 145 million light-years distant with virtually the same redshift as Arp 223. It is a ring galaxy which often is the result of an encounter. Neither shows any tidal streamer that you'd expect from an encounter so probably the experts are right, still, I have to wonder a bit. But see its near-twin Arp 222.
