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 135,000 light years, is bigger than the Milky Way. Over 100 billion stars are in the galaxy. [4] It was first discovered by Friedrich Winnecke of Karlsruhe, Germany, on 17 December 1868, while he was searching for comets. [5]

NGC 6786 is an interacting spiral galaxy 350 million light years from the Earth, in the constellation of Draco. NGC 6786 is currently interacting with LEDA 62867, and, being the larger galaxy, it is likely that NGC 6786 will absorb LEDA 62867 in the future. Both galaxies appear to be undergoing a starburst, a phenomenon commonly seen among interacting and merging galaxies.

NGC 986 is a barred spiral galaxy in the southern constellation of Fornax, located about 76 million light-years away. It was discovered on August 5, 1826 by the Scottish astronomer James Dunlop, who described it as a "faint nebula, of an irregular round figure". The galaxy has an angular size of 3′.8 × 1′.9 with a visual magnitude of 10.9. It belongs to the Fornax Cluster of galaxies. This galaxy has a nearby companion, NGC 986A, at an angular separation of 17′, corresponding to a projected separation of 110 kpc. The two appear unconnected.

<span class="mw-page-title-main">NGC 1317</span> Galaxy in the constellation Fornax

NGC 1317 is a barred spiral galaxy in the constellation Fornax, in the Fornax cluster. It was discovered by Julius Schmidt on January 19, 1865. It appears to be interacting with the much larger NGC 1316, but uncertainty in distance estimates and scales of tidal distortions make this uncertain. It is a member of the NGC 1316 subgroup, part of the Fornax Cluster. Its size is 2.8' x 2.4' which, at the average distance, gives a diameter of 55,000 light-years.
