S / 2004 S 34 is one of the smaller outer moons of the planet Saturn .
Discovery and naming
S / 2004 S 34 was discovered on December 12, 2004 by the astronomers Scott Sheppard and David Jewitt ( University of California ) and Jan Kleyna ( University of Hawaii ) on images taken from December 12, 2004 to March 22, 2007 with the 8.2 m Subaru telescope at the Mauna Kea Observatory . From this period 19 more moons of Saturn could be detected; the discovery was announced on October 8, 2019, the moon was given the provisional designation S / 2004 S 34 .
The Carnegie Institution for Science called with the announcement of the discovery on the public to to 6 December 2019 to send in suggestions for names for a total of 20 newly discovered moons. According to the group affiliation of the moons, names of giants from the Gallic , Nordic or Inuit mythology should be used.
The observation period of S / 2004 S 34 extends from December 12, 2004 to March 21, 2007; there are a total of 29 observations over a period of three years.
Track properties
S / 2004 S 34 orbits Saturn in three years and 319.2 days in a moderately elliptical, retrograde orbit between 18,583,125 km and 30,014,700 km from its center. The orbital eccentricity is 0.235, the web is 166.0 ° relative to the equator of Saturn inclined .
The moon is part of the so-called Nordic group of Saturn moons, which orbit the planet with orbital inclinations between 145.2 ° and 177.5 ° and orbital eccentricities between 0.130 and 0.580 retrograde.
Physical Properties
S / 2004 S 34 has a diameter of about 3 km. The absolute brightness of the moon is 16.1 m .
