Object name: IIZw073
Designation(s): IIZw073, UGC09796,
II Zw 073 is a very strange pair of galaxies in northeastern Bootes about a quarter billion light-years from us. Individually they are UGC 9796 and MCG +07-31-049. At that distance, you might not think there is much to see but the western galaxy UGC 9796 is a polar ring galaxy with a huge polar ring. While the galaxy itself is rather small with a diameter of its spiral disk being 28,000 light-years across the polar ring is about 115,000 light-years across. Its polar ring is 4 times the size of the galaxy. A very strange situation indeed. The UGC's original entry in 1973 reads: "Diffuse 'spindle' (dwarf?) with elongated 'core', probably superimposed companion". This was before polar ring galaxies were really known so the confusion isn't surprising. More surprising to me is that it is an entry in the Flat Galaxy Catalog! It is listed in the addenda catalog as FGC 224A (the "A" identifies it as an entry in the addenda catalog Apparently they are considering the polar ring the plane of the galaxy. Even then the length is only about 4 times the width, not 7 times needed to make the FGC.
