Ijiraq ( Saturn XXII) is one of the smaller outer moons of the planet Saturn.
The discovery of Ijiraq by a team consisting of Brett Gladman, John J. Kavelaars, Jean -Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsden, Philip D. Nicholson, Joseph A. Burns on recordings from September 23 to 4 November 2000, announced on 18 November 2000. Ijiraq first received the provisional designation S/2000 S 6 was named after the moon Ijiraq, a giant from the mythology of the Inuit.
Ijiraq orbiting Saturn on an eccentric orbit at an average distance 11.442 million km in about 451 days and 11 hours. The orbital eccentricity is 0.3215, the web is highly inclined with 46.750 ° to the ecliptic, which from Saturn represents the Laplace plane at this distance.
Ijiraq belongs to the Inuit group of Saturn's moons.
Structure and physical data
Ijiraq has a diameter of 10 km. Its density is 2.3 g/m3 compared to the other Saturn moons relatively high. He is probably composed of water ice with a high proportion of silicate rock. He has a very dark surface with an albedo of 0.06, that is, only 6% of the incident sunlight is reflected. With an apparent magnitude of 22.6 m is an extremely light faint object.
