Fornjot är en av Saturnus månar. Den upptäcktes av Scott S. Sheppard, David C. Jewitt, Jan Kleyna och Brian G. Marsden 2004, och gavs den tillfälliga beteckningen S/2004 S 8. Den heter också Saturn XLII.[1]
Fornjot är 6 kilometer i diameter och har ett genomsnittligt avstånd på 22 200 000 kilometer från Saturnus. Den har en lutning av 168° till ekliptikan (160° Saturnus ekvator) i en retrograd riktning och med en excentricitet på 0,186.
Fornjot namngavs efter Fornjót som var en jätte i den nordiska mytologin.[1]

Montage of Saturn and several of its satellites, Dione, Tethys, Mimas, Enceladus, Rhea, and Titan. JPL image PIA01482: Saturn System Montage This montage of images of the Saturnian system was prepared from an assemblage of images taken by the Voyager 1 spacecraft during its Saturn encounter in November 1980. This artist's view shows Dione in the forefront, Saturn rising behind, Tethys and Mimas fading in the distance to the right, Enceladus and Rhea off Saturn's rings to the left, and Titan in its distant orbit at the top.

Cropped version of N00084012.jpg, showing the brightest object in the frame - which may not be Fornjot. N00084012.jpg was taken on May 31, 2007 and received on Earth May 31, 2007. The camera was pointing toward S8_2004, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2008.
