NGC 1398 is an isolated barred spiral galaxy located 65 million light years from the Earth in the constellation of Fornax. The galaxy, with a diameter of 135,000 light years, is slightly larger than the Milky Way.
The galaxy features a bar with a very bright central bulge and a dense bright inner ring with a rope-like structure. The ring is actually two spiral arms that are closed in on each other. In contrast to its well-defined center, NGC 1398 has rather faint, flocculent, nearly circular spiral arms which start tangent to the ring and extend out close to a full revolution, accented by bright well defined regions.
