NGC 1398 is an isolated barred spiral galaxy exhibiting a double ring structure. It is located 65 million light years from the Earth, in the constellation of Fornax.[2][3] The galaxy, with a diameter of approximately 292,000 light years, is bigger than the Milky Way. Over 100 billion stars are in the galaxy.[4] The discovery credit for NGC 1398 is often given to Friedrich Winnecke of Karlsruhe, Germany, who observed it on 17 December 1868, while he was searching for comets.[5] German astronomer Wilhelm Tempel had first observed it on 9 October 1861, but he did not publish his observation until 1882.[6]
