This
Astrobin Debut Object, also known as UGC 827, is a pair of magnitude 16 galaxies located in the constellation of Pisces at a declination of +15 degrees. In his
Arp catalog, Dr. Arp classified this object into the category of Elliptical and Elliptical-like Galaxies Close to and Perturbing Spirals.
The left galaxy of the pair, an elliptical or lenticular galaxy, is LEDA 200189. It located 530 million light years away. This galaxy spans 1 arc-minute in our apparent view, which corresponds to a Milky Way like diameter of 120,000 light years.
The face-on barred ring spiral galaxy is LEDA 4645 is a bit further away, located 580 million light years away. Visually, it does appear to be located just behind the elliptical. This spiral spans 30 arc-seconds in our apparent view, which corresponds to a diameter of 70,000 light years.
Contrary to Dr. Arp’s categorization, these 2 galaxies are not close enough to each other to be interacting, and indeed no disturbance of either galaxy is seen in the image. There is a hint of a faint galactic halo just above and right of the spiral which gives the appearance of interaction, but I think that is just part of a very faint outer disk of the spiral.
The edge-on spiral to the upper left of Arp 128 is LEDA 1465229, an 80,000 light year diameter galaxy located 800 million light years away.
