Mundilfari (Saturn XXV) – księżyc Saturna, odkryty przez B.J. Gladmana i jego zespół w 2000 roku.

Krąży on po odległej orbicie, przeciwnie do kierunku obrotu planety. Zalicza się go do grupy nordyckiej księżyców Saturna. Mundilfari to imię jednego z olbrzymów w mitologii nordyckiej.

Instrument: Imaging Science Subsystem - Narrow Angle

Saturn's peaceful beauty invites the Cassini spacecraft for a closer look in this natural color view, taken during the spacecraft's approach to the planet. By this point in the approach sequence, Saturn was large enough that two narrow angle camera images were required to capture an end-to-end view of the planet, its delicate rings and several of its icy moons. The composite is made entire from these two images.

Moons visible in this mosaic: Epimetheus (116 kilometers, 72 miles across), Pandora (84 kilometers, 52 miles across) and Mimas (398 kilometers, 247 miles across) at left of Saturn; Prometheus (102 kilometers, 63 miles across), Janus (181 kilometers, 113 miles across) and Enceladus (499 kilometers, 310 miles across) at right of Saturn.

The images were taken on May 7, 2004 from a distance of 28.2 million kilometers (17.6 million miles) from Saturn. The image scale is 169 kilometers (105 miles) per pixel. Moons in the image have been brightened for visibility.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Office of Space Science, Washington, D.C. The Cassini orbiter and its two onboard cameras, were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

Animation of three discovery images of Saturn's irregular moon Mundilfari (S/2000 S 9; circled), taken by the 3.6-meter Canada-France-Hawaii Telescope (CFHT) on 23 September 2000. Each image was taken approximately 90 minutes apart, showing the moon's motion relative to the background stars and galaxies. The vertical streak of light is a diffraction spike from a nearby bright star at magnitude 9.4. The raw image datasets used are 550466p, 550476p, and 550488p. For comparison, the star field in these images can be viewed at the CDS's Aladin star atlas.
