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]

Supernovae

Two supernovae have been observed in NGC 1398:

• SN 1996N (Type Ib/c, mag. 16) was discovered by the Perth Astronomical Research Group on 12 March 1996. ^{[7] [8]}
• SN 2025zi (Type Iax [02cx-like], mag. 20.07) was discovered by BlackGEM on 21 January 2025. ^[9]
