Description

This object is a pair of spiral galaxies located 230 million light years away in the constellation of Pegasus at a declination of +9 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Double Galaxies.

The bottom galaxy is NGC 7469. This magnitude 12 galaxy spans 1.7 arc-minutes in our apparent view, which corresponds to a Milky Way size diameter of 120,000 light years. It has an interesting structure - a double ring galaxy with a bright core. As indicated by the bright core, this is a Seyfert galaxy. A small galaxy appears to the left of the disk but I believe that this is a distant galaxy, not a small companion.

IC 5283 is the spiral galaxy above NGC 7469. Star formation, in terms of star clusters and HII regions, appear to be lighting up the inner ring. This galaxy appears to have a small companion to the upper left, connected to it by a faint star stream bridge.

Although several sources say that these 2 galaxies are interacting, I don’t see distinct signs of connecting star streams in any of the images. It is not clear to me whether the star stream tail of IC 5283, extending up and to the right, is due to interaction with its small companion or with NGC 7469, or both.
