Erriapus ( Saturn XXVIII) is one of the smaller outer moons of the planet Saturn.

Discovery

The discovery of Erriapus 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 until 27 November 2000, it was announced on 7 December 2000. Erriapus first received the provisional designation S/2000 S 10 It was named after the moon Erriapus, a giant from Celtic mythology. By December 2007, the moon was due to an error the name Erriapo, the dative form of the name Erriapus. The name by the IAU decision was changed to Erriapus.

Path data

Erriapus orbiting Saturn on an eccentric orbit at an average distance of 17,604,000 km in 871 days and 6 hours. The orbital eccentricity is 0.4740, the web is highly inclined with 34.469 ° to the ecliptic, which from Saturn represents the Laplace plane at this distance.

Erriapus part of the Gallic group of Saturn's moons.

Structure and physical data

Erriapus has a diameter of only 8 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 23.0 m, it is an extremely light faint object.
