    Loge or Saturn XLVI is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 26 June 2006, from observations taken between January and April 2006.

    Loge is about 5 kilometres in diameter, and orbits Saturn at an average distance of 23,142,000 km in 1314.364 days, at an inclination of 166.5° to the ecliptic (165.3° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.1390. It has a tentative rotation period of about 6.9±0.1 hours, [2] but this is highly uncertain as the light curve is the shallowest among all the irregular moons studied by Cassini–Huygens (amplitude about 0.07 magnitudes). [3]

    It was named in April 2007, after Logi, a fire giant from Norse mythology.

    Fenrir, or Saturn XLI, is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on May 4, 2005, from observations taken between December 13, 2004, and March 5, 2005. Fenrir has an apparent magnitude of 25, making it one of the faintest known moons in the Solar System, and was discovered using some of the largest telescopes in the world. It is even too dark to have been observed by the Cassini spacecraft when it was in orbit around Saturn, for which it never got brighter than approximately 17th apparent magnitude. Fenrir was named after Fenrisulfr, a giant wolf from Norse mythology, father of Hati and Skoll, son of Loki, destined to break its bonds for Ragnarök.

    <span class="mw-page-title-main">Greip (moon)</span> Moon of Saturn

    Greip or Saturn LI is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 26 June 2006, from observations taken between 5 January and 1 May 2006. Greip is about 5 kilometres in diameter, and orbits Saturn at an average distance of 18,066 Mm in 906.556 days, at an inclination of 172.7° to the ecliptic, in a retrograde direction and with an eccentricity of 0.3735, and is presumably at high risk of eventually colliding with Phoebe. It is unknown whether Greip is more similar to Suttungr or Hyrrokkin in color. Its rotation period is most likely 12.75±0.35 hours with two minima in the light curve, but a longer period of 19 hours cannot be ruled out due to the short observation time by Cassini–Huygens.
